H25.0.2
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. All 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, SEVERE
PERSONAL INJURY OR DEATH.
YOUR GAS SUPPLIER SHOULD PERIODICALLY INSPECT AND CLEAN THE AIR VENT
SCREEN TO PREVENT ANY OBSTRUCTION. KEEP PROTECTIVE REGULATOR COVER IN
PLACE, AS EXPOSURE TO THE ELEMENTS CAN CAUSE ICE BUILDUP AND REGULATOR
FAILURE.

2.1 GENERAL SAFETY RULES
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.
