WHEN AN EXISTING CATEGORY I HEATER IS REMOVED OR
REPLACED, THE ORGINAL VENTING SYSTEM MAY NO LONGER
BE SIZED TO PROPERLY VENT THE ATTACHED APPLIANCES.
The effects of an improperly sized venting system can
include but not limited to: the formation of
condensate, leakage, spillage etc. The following test
procedure is required:
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected
to the venting system being placed into operation could result in carbon
monoxide poisoning or death.
The following steps shall be followed for each appliance connected to
the venting system being placed into operation, while all other
appliances connected to the venting system are not in operation:
1) Seal any unused openings in the venting system.
2) Inspect the venting system for proper size and horizontal pitch, as
required in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the
Natural Gas and Propane Installation Code, CSA B149.1 and these
instructions. Determine that there is no blockage or restriction,
leakage, corrosion and other deficiencies which could cause an
unsafe condition.
3) As far as practical, close all building doors and windows and all
doors between the space in which the appliance(s) connected to
the venting system are located and other spaces of the building.
4) Close fireplace dampers.
5) Turn on clothes dryers and any appliance not connected to the
venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they are operating at maximum speed. Do
not operate a summer exhaust fan.
6) Follow the lighting instructions. Place the appliance being inspected
into operation. Adjust the thermostat so appliance is operating
continuously.
7) Test for spillage from draft hood equipped appliances at the draft
hood relief opening after 5 minutes of main burner operation. Use
the flame of a match or candle.
8) If improper venting is observed during any of the above tests, the
venting system must be corrected in accordance with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or Natural Gas and
Propane Installation Code, CSA B149.1.
9) After it has been determined that each appliance connected to the
venting system properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace dampers and any
other gas-fired burning appliance to their previous conditions of use.

2.0 INSTALLER RESPONSIBILITY
WARNING:
FIRE OR EXPLOSION HAZARD
The heater and related gas piping and wiring must be installed only by individuals or firms well qualified and
licensed in the required field of work.
Read and understand this manual in its entirety BEFORE you install this heater. If you have any questions call
your local representative. Verify that the fuel on the installation site is the same as what is required for this
heater. Check heater for damage or missing parts. If damage has occurred, notify carrier or point of purchase
at once for reconciliation of damaged goods. We are not responsible for transit damage. Do not install if
heater is damaged.
If you do not understand any of the safety or hazardous warnings contained in this manual, or have
questions or concerns about the installation, operation, maintenance or service of this heater, or any other
questions or concerns relating to this heater, you MUST CALL THE FACTORY at the telephone number noted
on the front cover of this manual or as detailed on the rating plate on the heater before operating this
heater.
Verify that model, input & length is what was ordered and is appropriate for installation. If heater is too small
for the heating load of the building, property damage can occur due to freezing. If unit is too large, severe
heat damage call occur to the building and/or its contents, fire, explosion, injury or death. If in doubt compare
heat loss of building with unit on site. If you are unable to calculate heat loss, call your local representative
for assistance.
Installation shall be in accordance with local codes. (See ‘CODE COMPLIANCE’).
If installation requires tilting, DO NOT over tilt the unit. Units are certified for installations up to 45°; however,
the maximum recommended tilt is 25°.
Install unit according to the “Clearance to Combustibles” for that particular heater and type of installation.
Make sure that clearances are maintained from vehicles parked below or in front of heater. Take into
consideration hoists. Failure to do so could result in property damage, injury or death.
Make sure unit is adequately suspended from ceiling or roof. Select hanging location that has adequate
strength to support heater.
This heater needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air. In the USA, do not operate this heater without installing air intake hood or
duct (pin #800209) and exhaust/chimney vent in a residential garage application. In Canada, the outside air
intake is optional for residential garages. This heater must not be connected to a chimney flue serving a
separate solid-fuel burning appliance. This heater must only be installed with the venting that it is certified
for. Refer to the installation instructions for installation details. See pages 34 & 35)

6.0 INSTALLATION CLEARANCES AND CLEARANCE TO COMBUSTIBLES
Installation of overhead heaters in garages or hangars MUST meet the requirements for bottom (below)
clearances detailed in CANADA: Natural Gas and Propane Installation Code, CSA B149.1 or latest edition or
USA: National Fuel Gas Code, ANSI Z223.1/NFPA 54, or latest edition.
WARNING: In all situations, clearances to combustibles must be maintained. Minimum clearance
from heater must be maintained from vehicles parked below heater. The posting of signs may be
required in storage areas referring to clearances to combustibles to the heater and/or limiting the
stacking height of stored Items near the heater specifying a maximum height. Clearances are not for
use in four (4) sided enclosures. Certain materials or items, when stored under the heater, will be
subjected to radiant heat and could be seriously damaged.
WARNING:The stated clearance to combustibles represents a surface temperature of 90°F (32°C)
above room temperature. Building material with low heat tolerance (such as plastics, vinyl siding,
canvas, tri-ply, etc) may be subject to degradation at lower temperatures. It is the installer's
responsibility to assure that adjacent materials are protected from degradation. When in doubt, check
heat tolerance of building material(s) with their manufacturer.
END CLEARANCES
(BURNER HEAD END)
Minimum clearances from air intake end of burner head to object is 12" (30.5 cm).
Provide adequate accessibility clearances for servicing and proper operation. Do not install unit in such a
manner that the combustion air entering the heater is reduced in any manner

IN THE USA: Residential Garage heater installations with less than an 8' (2.44 m) clearance from the bottom
of the tube to the floor require the installation of the Protective Screen Kit PIN#3900212 (see page 20 for
details) The minimum floor clearance is 6' (1.83 m) from the floor to the bottom of the reflector.
IN CANADA: Residential Garage heater installations with less than an 7' (2.14 m) clearance from the bottom
of the tube to the floor require the installation of the Protective Screen Kit PIN#3900212 (see page 20 for
details) The minimum floor clearance is 6' (1.83 m) from the floor to the bottom of the reflector.
WARNING: In all situations, clearances to combustibles must be maintained. Minimum clearance
