This heater is not intended to be used at temperatures above 60°F (15°C). Use of this heater
at above this temperature may result in the burner locking out on the over temperature switch.
For operating conditions that will be at 8°F (-14°C) and below, it is recommended to reduce
the nozzle size to 3.5 GPH 45°B and make the appropriate air adjustments to compensate for
the increased density of fuel oil at lower temperatures.
See below for nozzle sizing
in low temperature applications.

PRE-INSTALLATION CHECKLIST
COMBUSTION AIR SUPPLY
The burner requires combustion air and ventilation air for reliable operation. Assure that the
Building and/or combustion air openings comply with National Fuel Gas Code NFPA 54/CSA B149. For
appliance/burner units in confined spaces, the room must have an air opening near the top of the room
plus one near the floor, each with a free area at least one square inch per 1000 Btu/hr input of all fuel
burning equipment in the room. For other conditions, refer to NFPA 31 (CSA B139 in Canada).
If there is a risk of the space being under negative pressure or of exhaust fans or other devices depleting
available air for combustion and ventilation, the appliance/burner should be installed in an isolated room
provided with outside combustion air.
CLEARANCES
The unit must be installed with minimum clearances of 6 inches on the sides, 18 inches from the top of
the unit and 36 inches from the burner access side. The unit can be installed on a level combustible floor.
Flue clearance is 18".
DUCT INSTALLATION

HIGH LIMITS
- The heater is supplied with manual reset high limits located behind marked panels on the left
side of the heater
- The high limit contacts are normally closed and open on the over temperature condition
- If a high limit trips allow the heater to cool down and then reset the high limit by manually
depressing the reset button located in the centre of the high limit.
-Duct diameter is 16 inches
-Use belt cuff ducting. Slide the cuff overtop of the duct inlet/outlet and tighten with the belt.
-The top two connections are the heated supply air into the building.
-The bottom two duct connections are for cold air or return air into the heater.
-The heater is approved use with or without ducting.
-Maximum duct length is 100 feet per supply opening. If return air ducting is used the length of the
return air duct must be subtracted from the allowable supply ducting length (i.e. if the return air
duct length is 30 feet the maximum supply duct length is reduced to 70 feet).
-Ducts should be rated for 300°F minimum.

VENT SYSTEM
The flue gas venting system must be in good condition and must comply with all the applicable codes.
OUTDOOR INSTALLATIONS:
,For outdoor installation vent cap must be installed and fastened.
:INDOOR INSTALLATIONS 3Must be done in accordance to NFPA 54 (or CSA B1 9) with local authorities having jurisdictions.
1. The flue must be securely attached to the unit with tight joints.
2. The flue must not be sized to have a cross-sectional area less then that of the flue
collar at the unit.
3. Other appliances must not be connected so as to vent through the vent of this unit.
4. Do not use 90-degree tees or elbows greater than 45 degrees.
5. Do not support the weight of the stack on the flue connection of the heating system.
6. The maximum flue gas temperature is +/- 550°F. “A” vent, or single wall steel pipe
must be used.
7. Minimize connecting pipe length and the number of bends by locating the unit as close
to the flue pipe as possible.
8. Maintain clearances between the flue pipe and combustible materials that are
acceptable to the Federal, Provincial and local authorities having jurisdiction.
9. Unit must be connected to a flue having sufficient draft to ensure proper operation of
unit.
VERTICALLY VENTED UNITS
1. Maximize the height of the vertical run of
vent pipe. A minimum of five (3) feet (1m)
of vertical pipe is required. The top of the
vent must extend at least two (2) feet
(0.61m) above highest point on the roof.
A weatherproof vent cap must be installed
to the vent termination.
2. Horizontal runs must not exceed 75% of
the vertical height of the vent pipe, up to a
maximum of ten (10) feet (3m).
Horizontal runs should be pitched upward
¼”per foot
(21 mm) and should be supported at 3
foot (1m) maximum intervals.
3. Design vent pipe to minimize the use of
elbows. Each 90 is equivalent to 5 feet
(1.5m) of straight vent pipe run.
4. Vent pipe should not be run through
unheated spaces. If such runs cannot be
avoided, insulate vent pipe to prevent
condensation inside vent pipe. Insulation
should be a minimum of ½”(12.7mm)
thick foil faced fibreglass, minimum 1 ½#

BEARING INSTALLATION AND MAINTENANCE
NOTE: To prevent premature failure –please ensure greasing instructions below are applied. As well,
tighten bearing set screws, collars, and wheel lugs every four to six months.
ENGINEERING – BALL & ROLLER BEARINGS LUBRICATION
For bearings that are equipped with a hydraulic grease fitting threaded into the housing for ease of
lubrication, the proper amount of lubricant in the bearing is important. Both excessive and inadequate
lubrication may cause failure. The bearings should be re-lubricated while they are rotating (if it is safe
to do so);; the grease should be pumped in slowly until a slight bead forms around the seals..The bead
in addition to acting as an indicator of adequate re-lubrication provides additional protection against the
entry of foreign matter and helps flush out contaminates in the bearing.
If necessary to re-lubricate while the bearing is idle, refer to the recommended re-lubrication grease
chart tables on the following page for various sizes of the bearings.
LUBRICANT- STANDARD BEARINGS
All bearing units are pre-lubricated at the factory This lubricant is satisfactory for an operating
temperature range of -40° to +250° F.
Select synthetic or standard industrial grade greases that conform to the following specification for
optimum bearing performance:
Premium Duty Ball & Roller;
58-75 SUS @ 210°F
50-750 SUS @ 100°F
NOTE: For heavy loaded roller bearing applications, grease with EP additives are often recommended for optimum performance.

A high quality synthetic wide temperature range grease is recommended.
Under most circumstances the fan bearings of the IHS700P will be operating within the 1500-2800 RPM range and will
be at temperatures at or below 120°F - 130°F. Therefore typical lubrication frequency of the bearings will be every 2 to 5
months. In very dirty air environment the frequency of lubrication should increase.
The following chart gives the frequency of re-lubrication based upon continuous operation for various operating
temperatures and can be used as a satisfactory guide for determining when bearings should be re-lubricated.

TENSIONING V-BELT DRIVES
1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.
2. Check tension frequently during the first 24-48 hours of operation.
3. Over-tensioning shortens the belt and bearing life under-tensioning reduces belt life and will
decrease performance and waste energy.
4. Keep belts free from foreign material that may cause slip.
5. Make V-drive inspection on a periodic basis. Tension when slipping. Never apply belt dressing
as this will damage the belt and cause early failure.
Check and tighten belt tension. The following procedure is recommended for tightening belts:
a) Measure span “X”shown in Figure A.
b) At the center of span length “X”, apply a force perpendicular to the span and large enough to deflect
belt 1/64”for each inch of span length. Example- the required deflection for a 40”span would be
40/64”or 5/8”.
c) Compare the force applied with the values given in Table III. If force is between the minimum and
maximum range shown, the drive tension should be satisfactory. A force below the minimum value
indicates an under tightened belt and force that exceeds the maximum value indicates an over
tightened belt.
