REGULATOR VENT
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 first stage regulator located at the tank outlet valve. All of these regulators (located outdoors) will have a vent; see Fig. 2 (below).

Keep free of ice, snow, and debris
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.
Your gas supplier should periodically inspect and clean the air vent screen to prevent any obstruction. Keep the protective regulator cover in place, as exposure to the elements can cause ice buildup and a regulator failure.
WARNING
AN OBSTRUCED AIR VENT ON AN LP (PROPANE) CYLINDER OR TANK REGULATOR CAN CAUSE EXPLOSION OR FIRE RESULTING IN PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR DEATH.
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, clothing, etc. This applies especially to gasoline and other flammable vapors and liquids.
2.A furnace needs adequate amounts of combustion and ventilation air to operate properly. Do not block or obstruct air openings on the furnace, or air openings supplying combustion or ventilation air to the area where the furnace is installed. There are many areas from which your furnace could be receiving combustion and ventilation 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 confined 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 qualified installation contractor, service agency or gas supplier, using factory specified or approved parts.
6.Familiarize yourself with the location of the furnace gas manual shutoff valve and any electrical switches, fuse or circuit breaker associated with the furnace.
7.For your protection, the furnace is equipped with manually reset flame rollout switches. If either switch trips frequently, do not ignore this, call your installation contractor, service agency or gas supplier.
8.Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the furnace before shutting off the electrical supply.
9.Familiarize yourself with the location of your furnace filter or filters. A blocked air filter will reduce efficiency, increase fuel consumption, raise the furnace operating temperature, and shorten the life of furnace components.
10.Do not cover return air grilles and supply air registers with drapes, curtains, throw rugs, etc.
11.Avoid shutting off supply air registers in the interests of saving heat. The furnace requires a sufficient quantity of air passing over the heat exchanger to operate within design temperatures, (system temperature rise). Reducing the availability of supply air registers may have the unforeseen consequence of raising the furnace operating temperature above design, thereby reducing furnace efficiency, and shortening the life of the furnace components.
