2.1 GENERAL SAFETY RULES
Most natural gas systems and all LP gas systems have a service
regulator located near the point where the gas piping enters the
building.
The propane tank will normally have an additional fi rst stage
regulator located at the tank outlet valve. Alll of these regulators
(located outdoors) will have a vent. (Figure 2)
It is important for these vents to remain clear. Do not allow moisture,
which could freeze, to build up in the vent. If you see moisture
building up in the regulator vent, contact your gas supplier.
OBSTRUCTION OF THE AIR VENT ON AN LP (PROPANE) CYLINDER OR TANK
REGULATOR CAN CAUSE EXPLOSION OR FIRE RESULTING IN PROPERTY
DAMAGE, SEVER PERSONAL INJURY OR DEATH.
YOUR GAS SUPPLIER SHOULD PERIODICALLY INSPECT AND CLEAN THE AIR
VENT SCREEN TO PREVENT ANY OBSTUCTION. KEEP PROTECTIVE REGULATOR
COVER IN PLACE, AS EXPOSURE TO THE ELEMNENTS CAN CAUSE ICE BUILD UP
AND REGULATOR FAILURE.

1. Combustible materials should not be stored against or around the furnace. Keep the furnace area clear
and free from all combustible materials such as newspapers, rags, cardboard, foam, plastic, paper backed
fi berglass insulation, clothing, etc. This applies especially to gasoline and other fl ammable vapors and liquids.
2. This furnace is CSA certifi ed as a Category IV indirect or direct vent appliance. It is designed to operate
as a single pipe (inside combustion air) or two pipe (outdoor combustion air) system. A furnace needs
adequate amounts of combustion air to operate properly. Do not block or obstruct the air-intake terminal on
the furnace, or air openings supplying combustion air to the area where the furnace is installed, if operating
as a single pipe system. There are many areas from which your furnace could be receiving combustion
air including from within the heated area (inside air), from outdoors, from an attic or crawl space. If
renovations are done, be sure that air supply openings are not inadvertently covered over with insulation,
vapor barrier, or similar construction material.
3. All doors and panels must be in place during normal furnace operation. Attempting to operate the furnace
with missing doors or panels could lead to the creation of carbon monoxide gas.
4. If the furnace is installed in a confi ned space or if you intend to build a furnace room where insulation
is present, be aware that some insulating materials are combustible. Do not allow building insulating
materials to come into contact with the furnace.
5. Any additions, alterations or conversions required in order for the furnace to properly match the application
requirements must be done by a qualifi ed installation contractor, service agency or gas supplier, using
factory specifi ed or approved parts.
6. Familiarize yourself with the location of the furnace gas manual shut-off valve and any electrical switch,
fuse or circuit breaker associated with the furnace.
7. Do not allow snow, ice or debris to accumulate around the outdoor furnace exhaust and combustion
air intake terminals. Blockage of the exhaust or combustion intake terminals can result in inadequate
performance or nuisance shut-downs.
8. Familiarize yourself with the location of your furnace fi lter or fi lters. A blocked air fi lter will reduce effi ciency,
increase fuel consumption, raise the furnace operating temperature, and shorten the life of furnace components.
9. Do not cover return air grills and supply air registers with drapes, curtains, throw rugs, etc.
10. Avoid shutting off supply air registers in the interests of saving heat. While there is some validity to this
practice with space heating, there is little to be gained in central heating systems. The furnace requires a
quantity of air passing over the heat exchanger to operate within design temperatures. Reducing the number
of supply air registers available for air delivery may have the unforeseen consequence of raising the furnace
operating temperature, reducing furnace effi ciency, and shortening the life of the furnace components.
