INSTALLATION REQUIREMENTS

Introduction

Please read these instructions completely and carefully before install-

ing and operating the furnace.

MODELS HTL-D AND HTLV-D

Models HTL-D and HTLV-D are oil red forced air up-ow furnaces

with an output capacity range of 89,000 BTU/Hr. to 140,000 BTU/

Hr.

CAUTION

DO NOT USE GASOLINE, CRANK CASE OIL, OR ANY

OIL CONTAINING GASOLINE.

FOR YOUR SAFETY:

DO NOT STORE OR USE GASOLINE OR OTHER

FLAMMABLE VAPORS AND LIQUIDS IN THE VICIN-

ITY OF THIS OR ANY OTHER APPLIANCE.

All models are CSA listed, (NRTL/C) for use with No. 1 (Stove) and

No. 2 (Furnace) Oil. Please refer to the tables on page 11 (Oil Burner

Setups) of this manual for performance and dimensional data.

In Canada, the installation of the furnace and related equipment

shall be installed in accordance with the regulations of CAN/CSA

- B139, Installation Code for Oil-Burning Equipment, as well as in

accordance with local codes.

In the United States of America, the installation of the furnace and

related equipment shall be installed in accordance with the regula-

tions of NFPA No. 31, Standard for the Installation of Oil-Burning

Equipment, as well as in accordance with local codes.

Regulations prescribed in the National Codes and Local regulations

take precedence over the general instructions provided in this instal-

lation manual. When in doubt, please consult your local authorities.

All models are shipped assembled and pre-wired. e furnace should

be carefully inspected for damage when being unpacked.

Heat Loss

e maximum hourly heat loss for each heated space shall be calcu-

lated in accordance with the procedures described in the manuals of

the Heating, Refrigeration and Air Conditioning Institute of Canada

(HRAI), or by other means prescribed, or approved by the local

authority having jurisdiction.

In the United States, Manual J. titled, "Load Calculation" published

by the Air Conditioning Contractors of America, describes a suitable

procedure for calculating the maximum hourly heat loss.

Location of Unit

e furnace should be located such that the ue connection to the

chimney is short, direct and consists of as few elbows as possible.

When possible, the unit should be centralized with respect to the

supply and return air ductwork. A central location minimizes the

trunk duct sizing. All models may be installed on combustible oors.

e minimum installation clearances are listed in

HEAT EXCHANGER SUPPORT SCREWS

Before nal placement of the furnace, the heat exchanger support

screws should be removed (See

Figure 1

). is may be preferable

if the furnace rear panel will be inaccessible aer installation. e

screws must be removed if the heat exchanger needs to be removed

from the cabinet.

Table 1 - Clearances

Figure 1 - Heat Exchanger Support Screws

LOCATION OF THE UNIT

Air Conditioning Applications

If the furnace is used in conjunction with air conditioning, the fur-

nace shall be installed in parallel with or upstream from the evapora-

tor coil to avoid condensation in the heat exchanger. In a parallel in-

stallation, the dampers or air controlling means must prevent chilled

air from entering the furnace. If the dampers are manually operated,

there must be a means of control to prevent the operation of either

system unless the dampers are in the full heat or full cool position.

e air heated by the furnace shall not pass through a refrigeration

unit unless the unit is specically approved for such service.

e blower speed must be checked and adjusted to compensate for

the pressure drop caused by the evaporator coil. Refer to page 18 of

this manual, for recommended wiring and electrical connections of

the air conditioning controls.

Combustion Air

If the furnace is installed in a closet or utility room, two openings

must be provided connecting to a well-ventilated space (full base-

ment, living room or other room opening thereto, but not a bed-

room or bathroom). One opening shall be located above the level of

the upper vent opening and one opening below the combustion air

inlet opening in the front of the furnace. Each opening shall have

a minimum free area of 1½ square inches per 1,000 Btu/h of total

input rating of all appliances installed in the room.

For furnaces located in buildings of unusually tight construction,

such as those with high quality weather stripping, caulking, windows

and doors, or storm sashed windows, or where basement windows

are well sealed, a permanent opening communicating with a well

ventilated attic or with the outdoors shall be provided, using a duct

if necessary. e duct opening shall have a free area of 1½ square

inches per 1,000 Btu/h of total input rating of all appliances to be

installed. When a furnace is installed in a full basement, inltration

is normally adequate to provide air for combustion and dra opera-

tion. Furnace rooms under 65m³ (2295 3) should automatically be

treated as conned space.

Chimney Venting

e ue pipe should be as short as possible with horizontal pipes

sloping upward toward the chimney at a rate of one-quarter inch to

the foot. e ue pipe should not be smaller in cross sectional area

than the ue collar on the furnace. e ue pipe should connect to

the chimney such that the ue pipe extends into, and terminates

ush with the inside surface of the chimney liner. Seal the joint

between the pipe and the lining. e chimney outlet should be at

least two feet above the highest point of a peaked roof. All unused

chimney openings should be closed. Chimneys must conform to

local, provincial or state codes, or in the absence of local regulations,

to the requirements of the National Building Code.

NOTICE

THE FURNACE IS APPROVED FOR USE WITH TYPE L

VENT OR EQUIVALENT.

CAUTION

CHIMNEY VENTED VERSIONS OF THE FURNACE

MUST BE CONNECTED TO A FLUE HAVING SUFFI-

CIENT DRAFT AT ALL TIMES TO ENSURE SAFE AND

PROPER OPERATION OF THE APPLIANCE.

NOTICE

THE RECOMMENDED FLUE DRAFT PRESSURE IS

-0.02 IN. W.C. (See

Figure 2

)

e ue pipe must not pass through any oor or ceiling, but may

pass through a wall where suitable re protection provisions have

been installed. Refer to the latest edition of CAN/CSA B-139 for

rules governing the installation of oil burning equipment. In the

United States, refer to the latest edition of NFPA 31 for regulations

governing the installation of oil burning equipment.

See Page 11, (Oil Burner Setups) of this manual for burner set-up.

Figure 2 - Checking Over-Fire Draft

Over-re dra access port

CONTROLS & CONNECTIONS

Barometric Damper Control

e barometric damper control, also known as a dra regulator,

is used on conventional chimney venting only. is control auto-

matically maintains a constant negative pressure in the furnace to

obtain maximum eciency. It ensures that proper pressures are

not exceeded. If the chimney does not develop sucient dra, the

dra control cannot function properly. e dra regulator, when

installed should be in the same room or enclosure as the furnace and

should not interfere with the combustion air supplied to the burner.

e control should also be located near the furnace ue outlet and

installed according to the instructions supplied with the regulator.

e ue outlet pressure (measured between the furnace and dra

regulator, or the oil burner mounting plate over-red dra access

port ,

Figure 2

) should be set to -0.02 in. w.c.

Fan Timer Board and Limit Control (FIG. 4) (page 21)

e Electronic Fan Timer integrates control of all burner and circu-

lator fan operations. is control is the central wiring point for most

of the electrical components in the furnace. e United Technolo-

gies 1158-120 (HTL-D) has an adjustable fan on time that is set by

selecting the dipswitch combination displayed in

Table 2

. is

fan on delay can be set at 30, 60 90 or 120 seconds. is provides a

delay between the burner ignition and blower start-up to eliminate

excessive ow of cold air when the blower comes on. e United

Technologies 1158-120 (HTL-D) has an adjustable fan o time of 1,

2, 4 or 6 minutes displayed in

Table 2

. e fan o delay time starts

when the burner motor is de-energized at the end of a call for heat.

Blower shutdown is delayed to remove any residual heat from the

heat exchanger and improve the annual eciency of the furnace.

e electronic fan timer board works in conjunction with snap disc

limit controls, which perform a safety function, and breaks power

to the oil burner primary control, which shuts o the burner if the

furnace over-heats. e limit control is thermally operated and

automatically resets. e limit control is factory installed, pre-set and

is not adjustable.

If the limit control opens with the United Technologies 1158-120

(HTL-D) electronic fan control, the circulating fan will be energized

as well. When the limit closes, the fan o timer will begin. At the

end of the fan o time cycle the burner will be energized, initiating a

normal burner cycle.

Fan Timer Board and Limit Control (Fig. 5) (Page 21)

e United Technologies 1168-1 ECM (HTLV-D) tap board has an

adjustable fan on/o delay that must be adjusted in accordance with

the furnace input rating (nozzle size).

Refer to Tables 8A and 8B

(pg 16 and 17)

Electrical Connections

e furnace is listed by the Canadian Standards Association un-

der the NRTL (North American) Standard. It is factory wired and

requires minimal eld wiring. All eld wiring should conform to

CAN/CSA C22.1 Canadian Electrical Code, Part 1, and by local

codes, where they prevail. In the United States, the wiring must be in

accordance with the National Fire Protection Association NFPA-70,

National Electrical Code, and with local codes and regulations.

e furnace should be wired to a separate and dedicated circuit in

the main electrical panel; however, accessory equipment such as

electronic air cleaners and humidiers may be included on the fur-

nace circuit. Although a suitably located circuit breaker can be used

as a service switch, a separate service switch is advisable. e service

switch is necessary if reaching the circuit breaker involves becoming

close to the furnace, or if the furnace is located between the circuit

breaker and the means of entry to the furnace room. e furnace

switch (service switch) should be clearly marked, installed in an eas-

ily accessible area between the furnace and furnace room entry, and

be located in such a manner to reduce the likelihood that it would be

mistaken as a light switch or similar device.

e power requirement for the HTL-D and HTLV-D models is: 120

VAC, 1 Ø, 60 Hz., 12A.

Accessories requiring 120 VAC power sources such as electronic

air cleaners and humidier transformers may be powered from the

electronic fan timer board where provisions have been made for con-

nections, but should have their own controls. Do not use the direct

drive motor connections as a power source, since there is a high risk

of damaging the accessories by exposure to high voltage from the

auto-generating windings of the direct drive motor.

ermostat wiring connections and air conditioning contactor low

voltage connections are shown in the wiring diagrams on page 18 of

this manual. Some micro-electronic thermostats require additional

controls and wiring. Refer to the thermostat manufacturer's instruc-

tions.

OIL BURNERS

e thermostat should be located approximately 5 feet above the

oor, on an inside wall where there is good natural air circulation,

and where the thermostat will be exposed to average room tempera-

tures. Avoid locations where the thermostat will be exposed to cold

dras, heat from nearby lamps and appliances, exposure to sunlight,

heat from inside wall stacks, etc.

e thermostat heat anticipator should be adjusted to the amper-

age draw of the heating control circuit as measured at the "R" and

"W" terminals of the thermostat. To reduce the risk of damaging the

heat anticipator, do not measure this current with the thermostat

connected to the circuit. Measure the amperage by connecting an

ammeter between the two wires that will connect to the thermostat

"R" and "W" terminals.

Humidier

A humidier is an optional accessory available through most heating

supply outlets. Installation should be carried out in accordance with

the humidier manufacturer's installation instructions. Water or

water droplets from the humidier should not be allowed to come

into contact with the furnace heat exchanger. Do not use direct drive

motor connections as a source of power for 120 VAC humidiers

and humidier transformers.

Piping Installation

e entire fuel system should be installed in accordance with the

requirement of CAN/CSA B-139, and local regulations. Use only ap-

proved fuel oil tanks, piping, ttings and oil lter.

In the United States the installation must be in accordance with

NFPA No. 31 and local codes and authorities.

Install the oil lter as close to the burner as possible. For further

details of the oil supply tank and piping requirements, please refer

to the instructions and illustrations in the oil burner and oil pump

instructions shipped with the furnace.

Oil Filter

All fuel systems should include an oil lter between the fuel oil stor-

age tank and the oil burner. When using an oil burner nozzle smaller

than 0.65 U.S. Gallons Per Hour, install an additional 7 to 10 micron

lter as close as possible to the oil burner.

Oil Burner Nozzles

e HTL-D and HTLV-D are certied for multiple ring rates, rang-

ing from 89,000 to 140,000 Btu/h. By manipulating the oil burner

nozzle, ame retention head, static plate and temperature rise; the

furnace may be red at an ideal rate for a wide range of structures.

Refer to Tables 3A, B and C,

page 11 and the furnace rating plate

to determine the proper combinations.

Oil Burner Adjustment

e burner air supply is adjusted to maintain the fuel to air ratio

to obtain ideal combustion conditions. A lack of air causes "so"

and "sooty" ames, resulting in soot build-up throughout the heat

exchanger passages. Excess combustion air causes a bright roaring

re and high stack temperatures resulting in poor fuel eciency. e

HTL-D and HTLV-D furnaces operate most eciently with a No. 1

smoke spot on the Bacharach Scale. is is not necessarily the opti-

mum setting; however, because dust will inevitably build up on the

air moving components of the oil burner assembly. is will result

in decreased air supply with the potential result of soot building up

in the ue gas passageways of the heat exchanger. Soot behaves as an

insulator and impairs good heat transfer. Stack temperature will in-

crease, and the overall eciency will decrease. As a means of avoid-

ing this problem, it is advisable to adjust the air supply to provide no

more than a trace smoke spot on the Bacharach Scale.

CAUTION

BEFORE OPERATING THE FURNACE CHECK BURN-

ER ALIGNMENT WITH COMBUSTION CHAMBER.

THE END CONE OF THE AIR TUBE MUST BE CEN-

TRED TO THE ACCOMMODATING RING PROVIDED

IN THE DESIGN OF THE COMBUSTION CHAMBER.

ADJUST AS NECESSARY.

Burner Electrodes

Correct positioning of the electrode tips with respect to each other,

to the fuel oil nozzle, and to the rest of the burner is essential for

smooth light ups and proper operation. Refer to the oil burner in-

structions shipped with the furnace for electrode specications.

NOTICE

Beckett AF Series Burner electrode specications have

been revised. ey should be adjusted to be 5/16” above

the nozzle centerline.

Burner Primary (Safety) Control

e furnace is equipped with a primary combustion control, some-

times referred to as the burner relay or burner protector relay, which

uses a light sensing device (cad cell) located in the burner housing,

to monitor and control combustion. Over time, dust or combus-

tion residuals can build up on the lens of the cad cell impairing its

response to the ame. e cad cell should be checked for cleanliness

and proper alignment if the primary control frequently shuts down

combustion.

CAUTION

ALL FURNACE CONTROLS ARE SENSITIVE AND

SHOULD NOT BE SUBJECTED TO TAMPERING. IF

PROBLEMS PERSIST, CALL YOUR SERVICE CON-

TRACTOR.

Combustion Chamber

is furnace is equipped with a high quality cerafelt combustion

chamber. It is held in place by a retaining bracket.

NOTICE

Check the alignment of the combustion chamber and

oil burner before ring. It is possible for the combustion

chamber to shi if subjected to rough handling during

transit.

CAUTION

DO NOT CONNECT POWER LEADS BETWEEN MO-

TOR SPEEDS. THE NEUTRAL WIRE MUST ALWAYS

BE CONNECTED TO THE MOTOR'S DESIGNATED

NEUTRAL TERMINAL.

If the joining of the blower speed wiring is done in the furnace junc-

tion box, tape o both ends of the unused wire.

Do not use the blower speed wires as a source of power to acces-

sories as electronic air cleaners and humidier transformers. e

unused motor taps auto-generate suciently high voltages to dam-

age accessory equipment.

WARNING

DISCONNECT THE POWER SUPPLY TO THE FUR-

NACE BEFORE OPENING THE BLOWER ACCESS

DOOR TO SERVICE THE AIR FILTER, FAN AND

MOTOR. FAILURE TO SHUT OFF POWER COULD

ALLOW THE BLOWER TO START UNEXPECTEDLY,

CREATING A RISK OF DEATH OR PERSONAL INJURY.

Circulating Air Blower (HTLV-D) - (See Page 10, ECM

BLOWER MOTOR OPERATION HTLVD)

COMBUSTION CHAMBER

Circulating Air Blower (HTL-D)

e HTL-D and HTLV-D furnace models are equipped with direct

drive blower systems. HTL-D models are equipped with PSC mo-

tors; HTLV-D models are equipped with electronically commutated

motors (ECM). Direct drive blower speed adjustments are not

normally required in properly sized extended plenum duct systems.

e motor RPM and air CFM delivery will vary automatically (on

ECM motor equipped models) to accommodate conditions within

the usual range of external static pressures typical of residential duct

systems. Under-sized duct systems may require a higher blower

speed to obtain a reasonable system temperature rise. Some older

duct systems were not designed to provide static pressure. ey

typically feature special reducing ttings at each branch run and lack

block ends on the trunk ducts. ese systems may require modica-

tion to provide some resistance to the airow to prevent over amping

of the direct drive blower motor. Selecting a lower blower speed may

correct this problem. Direct drive blower speeds are adjusted by

changing the "hot" wires to the motor winding connections. Please

refer to wiring diagrams on page 18 of this manual or the wiring dia-

gram label axed to the furnace. THE NEUTRAL WIRE (normally

the white wire) IS NEVER MOVED TO ADJUST THE BLOWER

SPEED.

It is possible and acceptable to use a single blower speed for both

heating and cooling modes. e simplest method to connect the

wiring from both modes is to use a "piggy-back connector" accom-

modating both wires on a single motor tap. It is also acceptable to

connect the selected motor speed with a pigtail joined to both heat-

ing and cooling speed wires with a wire nut. As a safety precaution

against accidental disconnection of the wires by vibration, it is advis-

able to secure the wire nut and wires with a few wraps of electricians

tape.

e combustion chamber should be inspected for damage or carbon

build up whenever the oil burner is removed for repairs or routine

maintenance.

CAUTION

DO NOT START THE BURNER UNLESS THE BLOWER

ACCESS DOOR IS SECURED IN PLACE.

CIRCULATING AIR BLOWER

MAINTENANCE AND SERVICE

Routine Maintenance By Home Owner

Other than remembering to arrange for the annual professional

servicing of the furnace by the service or installation contractor, the

most important routine service performed by the homeowner is to

maintain the air lter or lters. A dirty lter can cause the furnace to

over-heat, fail to maintain indoor temperature during cold weather,

increase fuel consumption and cause component failure.

e furnace lter(s) should be inspected, cleaned or replaced month-

ly. e furnace is factory equipped with a semi-permanent type lter.

If the lter is damaged, replace with lters of the same size and type.

(See Parts Listing Ref. No. 21).

During the routine service, inspect the general condition of the fur-

nace watching for signs of oil leaks in the vicinity of the oil burner,

soot forming on any external part of the furnace, soot forming

around the joints in the vent pipe, etc. If any of these conditions are

present, please advise your service or installation contractor.

Annual Service By Contractor

CAUTION

THE COMBUSTION CHAMBER (FIREPOT) IS FRAG-

ILE. USE CARE WHEN INSPECTING AND CLEANING

THIS AREA.

e heat exchanger should be inspected periodically and cleaned

if necessary. If cleaning is necessary, SHUT OFF POWER TO THE

FURNACE and remove the burner. Using a sti brush with a wire

handle, brush o scale and soot from inside the drum and ue pipe.

To clean the radiator, remove the clean-out caps screws, and remove

the caps carefully to avoid tearing the gaskets. A wire brush can be

used to loosen dirt and debris on the inside surfaces of the radiator.

Clean out all accumulated dirt, soot and debris with a wire handled

brush and an industrial vacuum cleaner. Before replacing the clean-

out caps, inspect the gaskets. If the gaskets are broken, remove the

remnants and replace with new gaskets.

e blower motor is factory oiled and permanently sealed. DO NOT

LUBRICATE. Excess oil causes premature electric motor failure.

Inspect the blower fan. Clean if necessary.

Oil Burner Maintenance: Follow the instructions of the oil burner

manufacturer. (See oil burner manufacturer's instructions supplied

with furnace or burner). It is advisable to change the oil burner

nozzle and oil lter on an annual basis.

e venting system should be cleaned and inspected for signs of

deterioration. Replace pitted or perforated vent pipe and ttings. e

barometric damper should open and close freely.

All electrical connections should be checked to ensure tight con-

nections. Safety controls such as the high limit controls should be

tested for functionality. e fan control should be checked to ensure

that the fan on and o delay function continues to start and stop the

blower fan at the optimal settings.

Before Lighting

Open all supply and return air registers and grilles.

Open all valves in oil pipes.

Turn on electric power supply.

side mid point of the transition is usually ideal, providing that the

thermometer probe is beyond the "line of sight" wherein false read-

ings from radiant heat could be observed. System temperature rise is

the dierence in temperature between the supply air and return air.

To check the operation of the limit switch, shut o power to the

furnace. Temporarily remove the neutral wire from the direct drive

blower motor. Restore the electrical power to the furnace and set the

thermostat above room temperature.

Aer three or four minutes of burner operation, the limit control

should turn the burner o. When the limit function test is complete,

shut o electrical power to the furnace, replace the neutral wire to

the blower fan motor, and then restore power. e blower fan will

start up immediately. Once the temperature has dropped and the

limit control has reset, the fan will operate until the fan o time is

achieved. e oil burner will then resume operation and continue

the 5 pin power plug to the blower fan motor, and then restore

power. e blower fan will start up immediately. Once the

temperature has dropped and the limit control has reset, the

fan will operate until the fan o time is achieved. e oil burner

will then resume operation and continue until the thermostat

is satised. Restore the thermostat setting to a comfortable

temperature.

NOTICE

IF THE FURNACE IS TO BE SHUT DOWN FOR AN

EXTENDED PERIOD OF TIME, CLOSE THE OIL SUP-

PLY VALVE TO THE BURNER.

CAUTION

DO NOT ATTEMPT TO START THE BURNER WHEN

EXCESS OIL HAS ACCUMULATED, WHEN THE

FURNACE IS FULL OF VAPOR, OR WHEN THE COM-

BUSTION CHAMBER IS VERY HOT. NEVER BURN

GARBAGE OR PAPER IN THE FURNACE, AND NEVER

LEAVE PAPER OR RAGS AROUND THE UNIT.

ECM BLOWER MOTOR OPERATION HTLVD

Setting Blower “ON” and “OFF” Timings

Blower on/o time delays are handled by ECM motor programming.

Features of this ECM variable speed motor are that it will deliver a

constant airow within a wide range of external static pressures, and

also includes:

Soft Start

: is ECM variable speed motor will slowly ramp up to

the required operating speed. is feature in the heating cycle allows

the heat exchanger to reach operating temperature before the blower

motor starts, which minimizes noise and increases comfort.

Soft Stop

: At the end of the heating cycle, the ECM variable speed

motor will slowly ramp down. is feature allows for increased

energy eciency and reduced noise levels.

Dehumidication

: A dehumidication feature has been pro-

grammed into the variable speed motor. At the start of each cooling

cycle, the variable speed motor will run at 82% of the rated airow

for 7.5 minutes. Aer 7.5 minutes has elapsed, the motor will

increase to 100% of the rated airow. is prole is used to provide

dehumidication and improve system eciency.

Continuous Fan Operation:

When the thermostat continuous

fan (G) switch is on without a call for heating or cooling, the indoor

fan is immediately energized up to 50% of the cooling speed. is

feature allows continuous circulation of air between calls for heating

or cooling.

If a call for heat (W) or cool (Y) occurs during continuous fan, the

blower will remain energized.
