technician. The furnace should be inspected before use and
at least annually by a professional service technician. More
frequent cleaning may be required due to excessive lint from
carpeting, bedding material, etc. It is imperative that control
compartments, burners, and circulating air passageways of
the furnace be kept clean.
14. Do not put anything around the furnace or vent cap that will
obstruct the flow of combustion and ventilation air.
15. When installing the furnace allow adequate accessibility
clearances for servicing and proper operation. (See figure 1 on
page 5).
16. The wall furnace should be located near the center of the area
to be heated for optimal heat distribution. If the wall furnace
is installed directly on carpeting, tile or any combustible
material other than wood flooring, the wall furnace shall be
installed on a metal plate or wood panel secured to the floor,
extending the full width and depth of the wall furnace. If a
side register kit is to be installed, see Page 16.

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.

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.
