BOILER RATINGS AND CAPACITIES
Before undertaking the installation of the HW check
the boiler rating plate to ensure that the boiler is the
proper size for the job. The "Net I=B=R Ratings" specify
the equivalent amount of direct cast iron radiation that
the boiler can handle under normal conditions. Also
ensure that the boiler has been set up for the type of
gas available at the installation site. Other important
considerations are the availability of an adequate
electrical supply, fresh air for combustion and a suitable
chimney or vent system.
NOTES:
1. For altitudes above 2000 ft, 610 m, ratings should
be reduced at the rate of 4% for each 1000 ft, 305
mabove sea level, 10% in Canada.
2. If ordering a boiler for use with LP gas add a P to
the model number, ie PHW.
BOILER LOCATION
.Locate the boiler in an area that provides good
access to the unit. Keep in mind that servicing may
require the removal of jacket panels. Accessibility
clearances must take precedence over fire
protection clearances.
2. An optimum site will be level, central to the piping
system, close to a chimney and have adequate
fresh air for combustion.
.Ensure that the floor is structurally sound and will
support the weight of the boiler. This boiler is
designed for non combustible floors only! A special
base supplied by Hydrotherm must be used if the
boiler is to be installed on a combustible floor.
NEVER USE A SUBSTITUTE BASE ON A
COMBUSTIBLE FLOOR! Never install this boiler on
carpeting!
.DO NOT install this boiler in a location that would
subject any of the gas ignition components to direct
contact with water or excessive moisture during
operation or servicing.
5. DO NOT place this boiler in a location that would
restrict the introduction of combustion air into the
boiler. NEVER store objects on or around the boiler.

Page4 HWNATURALORPROPANEBOILER
INSTALLATIONANDOPERATINGINSTRUCTIONS
,If the boiler is to be located in an alcove, closet or
other confined space the distances from the boiler
and it's vent system to all combustible construction
must be equal to or greater than the minimum
clearances in Figure 1. When installed in a closet or
confined space two permanent openings of equal
area adjoining another room or rooms having
sufficient volume to meet the requirements of an
unconfined space must be provided. Each opening
must have a minimum free area of one square inch
per 1000 Btu/hr, 2200 mm2/kWbased on the total
input rating of all gas utilization equipment in the
confined area. Each opening must be no less than
100 in 2, 64516 mm 2, in size. The upper opening
must be within 12 in, 305mm, of, but not less than
3 in, 76 mm, from the top of the enclosure. The
bottom opening must be within 12 in, 305 mm, of,
but not less than 3 in, 76 ram, from the bottom of the
enclosure.

INSTALLATION AND OPERATING INSTRUCTIONS
COMBUSTIBLE FLOOR OPTION
The HW boiler has been designed for use on
noncombustible floors only. If a HW boiler is to be
installed on combustible flooring of any type, it MUST
be installed using the Special Base designed by
Hydrotherm. Do NOT use any base other than the one
specifically designed for it if installing a HW boiler on
combustible flooring.
To order the Special Base contact the nearest
Hydrotherm distributor and ask for the "Noncombustible
Floor Pan" part number referenced in the Replacement
Parts List in back of the IOM.
Determine where the boiler will be located by following
the instructions in the Boiler Location section of this
manual. Place the Special Base in this location and
fasten it in place to prevent it from moving while the
boiler is being placed on it.
If the HW is being installed inan alcove or closet ensure
that the minimum distance to combustible construction
requirements, listed in Figure 1, are met.

Remove the sheet metal base pan attached to the
boiler. Position the boiler in front of the Special Base. It's
suggested that two lengths of 3" pipe the width of the
boiler, or longer, be placed under the boiler base side
panels.
COMBUSTION AiR
CAUTION: Be careful not to damage the burners,
pilot assembly or any other gas train components
during this procedure, if a component is damaged,
replace it!
Carefully roll the boiler up to the front of the Special
Base. Align the boiler base side panels with the Special
Base support channels. Using great care, slide the boiler
onto the Special Base.
CAUTION: Never lift the boiler by the jacket panels
or flue collector/draft diverter or severe damage to
the boiler may result!
Center the boiler from side to side on the Special Base.
Ensure that the back of the burner base side panels
are flush with the back of the Special Base support
channels. Install the front grill supplied with the Special
Base. Complete the installation in accordance with the
instructions set forth in this manual.

Page 6 HW NATURAL OR PROPANE BOILER
iNSTALLATiON AND OPERATING iNSTRUCTiONS
To operate properly and safely this boiler requires a
continuous supply of air for combustion. Oxygen is used
by the burners in the boiler to burn the gas. In addition,
air is also used to assist in the safe disposal of the
products of combustion. This air is known as dilution
air and mixes with the products of combustion to assist
in it's exit through the flue pipe and chimney. An
adequate supply of outside air must be available to
replace that used by these processes.
Older houses often have enough "leakage" to provide
an adequate amount of combustion air provided that
the demand for combustion air is not too great. Homes
that are relatively new or "tight" will most likely require
the installation of a fresh air duct or other means of
providing air for combustion. Any home utilizing other
gas burning appliances, a fireplace, wood stove or any
type of exhaust fan must be checked for adequate
combustion air when all of these devices are in operation
at one time. Sizing of an outside air duct must be done
to meet the requirements of all such devices.

If the boiler will be located in an alcove, closet or any
confined space refer to item 6 in the Boiler Location
section of this manual.
VENT CONNECTIONS
Always use a type B or C vent pipe of the proper
diameter for the boiler. Use the shortest, straightest
vent system possible for the particular application. The
vent system should be sloped up toward the chimney
at a rate of 1/4 in/ft, 2 mm/m. Ensure that the flue pipe
is properly supported and each connection securely
fastened with at least 3 corrosion resistant sheet metal
screws. The termination of the vent pipe should be
flush with the inside of the chimney flue.
Always provide a minimum clearance of 6 in, 152 mm,
between type C vent pipe and any combustible
materials. Type B1 vent may be used, clearance
between it and any combustible material must be as
listed.
CHIMNEY & VENT PIPE CONNECTIONS
Chimney inspection & Sizing
if this boiler will be connected to a masonry chimney, a
thorough inspection of the chimney must be performed.
Ensure that the chimney is clean, properly constructed
and properly sized. Table 1 lists the flue size and
chimney height required for this boiler.
When more than one appliance is connected to the
same chimney flue, the flue must be large enough to
handle both appliances.
The vent installation must be in accordance with Part 7
of the latest revision of the National Fuel Gas Code,
ANSI Z223.1/NFPA 54.
Common Vent Systems
If an existing appliance is removed from a common
venting system, the common venting system may then
be too large for the proper venting of the remaining
appliances connected to it. At the time of removal of
an existing boiler, the following steps shall be followed
with each appliance remaining connected to the
common venting system placed in operation, while the
other appliances remaining connected to the common
venting system are not in operation.
Au moment du retrait d'une chaudi_re existante, les

Vent Dampers
This boiler comes from the factory equipped with a
vent damper specifically engineered for it. The vent
damper must be properly installed to obtain the high
performance for which this boiler was designed. If the
damper is damaged or missing do not install the boiler
without it! Contact the nearest Hydrotherm distributor
to obtain the proper vent damper.
Vent dampers are designed for use with only one
appliance. NEVER connect more than one appliance
to a single vent damper.
Locate the vent damper so that it is accessible and the
damper position indicator is visible. Maintain a minimum
of 6 inches between the damper and any combustible
materials!

circulator must be provided. A circulator with a higher
capacity may also be used. Figure 5 depicts the
performance curve for the TACO 007 circulator.
Piping For Use With Cooling Units
The boiler, when used in connection with a refrigeration
system, must be installed so the chilled medium is piped
in parallel with the boiler. Appropriate valves must be
used to prevent the chilled water from entering the
boiler. See Figure 6 for the proper piping layout.
When a boiler is connected to a heating coil that may
be exposed to refrigerated air from an air handling
device, the piping system must be equipped with flow-
control valves or some other automatic means of
preventing gravity circulation of the boiler water during
the cooling cycle.

Pump Away Bypass
For systems that use a single circulator to pump away
from the boiler, the bypass should be installed on the
discharge side of the circulator, see Figure 8. Full
temperature water supplies the baseboard distribution
system as before. Half of the circulator's volume moves
through the bypass, blending and heating the cooler
return water. Again, the cost of installing the bypass is
small and setting it by temperature can be accomplished
with a contact thermometer.

An additional circulator can also be used to provide a
return water temperature blend. This method works
well with systems with multiple zones with circulators,
see Figure 9. The dedicated bypass circulator provides
a strong blending flow without diminishing the flow
available to any heating zone. Any residentially sized
circulator is adequate for this purpose.
Each of these bypass solutions also has the added
benefit of increasing circulation in the boiler which will
maximize tankless coil output and increase the accuracy
of temperature sensing controls.

Reverse Acting Aquastats
An alternative for existing systems experiencing
condensation that does not require re-piping the boiler
utilizes a reverse acting aquastat, one that makes on
temperature rise. This approach works best in single
zone systems. Wired in series with the circulator, this
control holds the circulator off until the boiler reaches
an acceptable temperature and then starts system
circulation, see Figure 10.
GAS SUPPLY PIPING
The most commonly available reverse acting aquastat
is a Honeywell L4006B. The aquastat should be
mounted in an immersion well directly installed in the
boiler. The use of heat conductive grease, Honeywell
part # 972545, in the immersion well is strongly
recommended for fast and accurate temperature
response. Set this adjustable aquastat to make at no
less than 130 ° F, 54°C. While this method can cause
the circulator to cycle more frequently, setting the
aquastat's differential to the maximum 25-30°F will
minimize short cycling.

If for any reason the boiler is not for the type of gas
available at the installation site, call the nearest
Hydrotherm distributor to resolve the problem.
Table 3 should be used to ensure that the gas supply
piping is sized properly. If more than one appliance is
supplied by the same supply pipe, the piping must be
sized based on the maximum possible demand. Do not
neglect the pressure drop due to pipe fittings. Table 4
should be used in conjunction with Table 3 to ensure
that the supply piping has the capacity to meet the
demand.

INSTALLATION AND OPERATING INSTRUCTIONS
Figure 11 depicts the proper way to connect the boiler
to the gas supply piping. The manual shut-off valve
MUST be installed in the supply piping. It should be
approximately 5 ft, 1.5 m above the floor. Provide a
drip leg/sediment trap at the bottom of the vertical
section of the gas supply pipe. A ground joint union
should be installed between the boiler gas controls

CAUTION: Always use a wrench on the gas valve
body when making gas connections to it. Never
over-tighten the piping entering the gas valve body.
Failure to comply with this caution may result in gas
valve failure!
Safe lighting and other performance criteria were met
with the gas manifold and control assembly provided
on the boiler. All gas connections MUST be leak tested
before putting the boiler into operation.
Whenever the gas supply piping is pressure tested the
boiler gas controls must be protected. If the test
pressure is equal to, or less than 1/2 psig, 3.5 kPa,
isolate the boiler by closing it's manual shut off valve,
see Figure 11. If the test pressure is greater than, or
equal to 1/2 psig, 3.5 kPa, disconnect the boiler and
it's individual shut-off valve.
CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation!
ATTENTION: Au moment de I'entretien des
commandes, _tiquetez tous les ills avant de les
d_brancher. Des erreurs de c_blage peuvent ent rafner
un fonctionnement in=ad_quat et dangereux.
S'assurer que I'appareil fonc-tionne ad_quatement
une fois I'entretirn termin_.
The electrical connections to this boiler must be made
in accordance with all applicable local codes and the
latest revision of the National Electrical Code, ANSI/
NFPA-70. Installation should also conform with CSA
C22.1 Canadian Electrical Code Part l if installed in
Canada. Install a separate 120 volt 15 amp circuit for
the boiler. A shut-off switch should be located at the
boiler. The boiler must be grounded in accordance with
the authority having jurisdiction, or if none, the latest
revision of the National Electrical Code, ANSI/NFPA-
70.
Line voltage field wiring of controls and other devices
must conform to the temperature limitation of type T
wire at 95°F, 35°C, above room temperature. Use
copper conductors with a minimum size of #14 awg.
Low voltage wiring must not be less than #18 awg with
a neoprene, thermoplastic or other equivalent insulation
having a minimum insulation thickness of 0.012 in,
0.3 mm.
Thermostat Installation
ALWAYS follow the instructions included with the
thermostat to be used to control the boiler. Proper
location of the thermostat will ensure efficient trouble-
free operation of the boiler. Mount the thermostat to an
inside wall at a height approximately five feet above
the floor. Avoid placing the thermostat in areas that will
not provide an accurate measurement of the room
temperature. Locating the thermostat behind a door, in
an alcove, close to a source of thermal radiation or in a
drafty area will cause poor or sporadic heating.
Vent Damper
The vent damper supplied with the boiler has been
wired with a 6 pin molex connector that will plug directly
into the boiler's wiring harness.

BOILER SET UP
NOTE: Before starting the boiler, turn off the
electrical supply going to it. Make sure that gas is
available at the combination control inlet. Open the
valves in the return and supply piping. Failure to
take these precautions will prevent the boiler from
operating properly.
Fill the boiler and all of the radiation with water. Make
sure that the system iscompletely purged of air.
Review these instructions and make sure that the boiler
installation complies with ALL of the stated instruction up
to this point.
Flame Roll=out Safety Shutoff System
The HW gas boiler isfitted with a flame roll-out switch
that detects the presence of hot flue gases in the control
compartment. If something prevents the combustion
products from property passing through the boiler, the
roll-out switch will shut the boiler off. If the flame roll-out
safety system is activated, contact qualified service
agency to correct the problem and reset the flame roll-
out safety switch. Do not attempt to start the boiler until
problem has been corrected and the switch has been
reset.
Never attempt to bypass the flame roll=out safety
shutoff switch for the purpose of operating the
boiler!
The boiler should be inspected and serviced before
each heating season by a qualified service agency. The
boiler flue passages, venting system, ignition
components and the burners should be cleaned and
examined for deterioration due to corrosion. All
operational characteristics of the boiler such as
combustion products, the ignitionsafety shutoff devices
and proper control function must be thoroughly checked
out.
During the heating season, the owner should check the
boiler and the area around it at least once a month.
Clear away all objects on or near the boiler. Ensure that
there is no discoloration of adjacent combustible
materials due to heat. If there is, IMMEDIATELY call the
installer or a qualified service agency.
