FRESH AIR FOR COMBUSTION AND VENTING
Adequate air for combustion and venting must be
provided. Any reduction in the necessary amount of
fresh air can result in an oxygen starved flame that
emits Carbon Monoxide (C.O.) an odorless, colorless
gas that can cause serious injury or death.
A ventilated crawl space will usually provide enough fresh
air. However, you must check to see that there is 1 square
inch of free area of ventilation opening for each 1,000 BTU’s
To compensate for the loss of square inches of
ventilation due to the use of louvers, grills, or screens add
approximately 50% to the square inches calculated. Screen
all openings with mesh not less than 1/4 inch to prevent
animals or insects from entering the crawl space.
All type “B” vents shall ext end in a generally vertical
direction with offsets not exceeding 45 degrees, except
that a vent system having not more than one 60 degree
offset may be allowed.
Any angle greater than 45 degrees from the vertical is
considered horizontal. The total horizontal run of a vent
plus the horizontal vent connector shall be not greater
than 75 percent of the vertical height of the vent.
Any offsets used should be as far above the drafthood
as possible to allow a venting action to begin before any
restriction is encountered.

WARNING: IMPROPER OR UNSAFE VENTING
PRESENTS A HAZARD THAT MAY RESULT IN
PROPERTY DAMAGE, BODILY INJURY OR LOSS OF
LIFE. LISTED BELOW ARE SOME GUIDELINES TO
OBSERVE WHEN INSTALLING THE VENT SYSTEM.
1. Never reduce the vent pipe to a size smaller than
the outlet on the draft hood.
2. Never run pipe more than 15 feet horizontally.
3. The total horizontal run of a vent plus the
horizontal vent connector shall be not greater
than 75% of the vertical height of the vent.
4. Slope horizontal pipe upwards at least 1/4 inch
per lineal foot.
5. Do not use more than one elbow. An elbow restricts
6. Use a noncombustible thimble when connecting
vent pipe to a masonry chimney.
7. Do not insert vent pipe farther than 1/4 inch into the
interior of the chimney.
8. Single wall pipe must not be used.
9. Never connect the vent pipe to any chimney or vent
system serving a solid fuel-burning appliance.
10. If another appliance is being vented through the
must be increased to compensate for the additional
load.
11. Never install any kind of damper in the vent system.
12. Do not use transite or any other type of ceramic
pipe for venting.
Class “B” double wall pipe is acceptable to most codes,
and if installed in accordance with the pipe manufacturers
system. Class “B” pipe has an integral lock for securing
together. Fasten pipe to draft hood using at least three self-
tapping sheet metal screws at equal intervals around the
circumference of the pipe. Support horizontal pipe at three-
foot intervals with metal strapping attached to joists.
proper size vent listed for each furnace on page 5.
We do not recommend doing so, but if you must vent
into a masonry chimney, use the following instructions.
chimney must be inspected to determine that it is clear
and free of obstructions and that it is safe for the intended
use. The inside of the chimney must be at least 6 inches
in diameter or 6 inches by 6 inches if rectangular. Insert
the vent pipe into the chimney through a masonry or
noncombustible corrosion-resistant thimble of the correct
diameter. Do not push the pipe farther than 1/4 inch into
the inside of the chimney. Figure 7A Pushing the pipe
farther into the inside of the chimney may cause partial or
complete blockage as illustrated in Figure 7B.
Even following these instructions you may still have a
venting problem because of the larger area to be heated
inside the chimney. This could cause pilot outage, odors
coming from the furnace, or noise due to excessive heat
not being vented out of the combustion chamber. If you
experience any of these problems, we recommend running
the proper size “B” type vent pipe down the chimney
and connecting to the horizontal run of vent pipe with a
90-degree elbow inside the chimney. Figure 7C
Extend the vent system at least 3 feet above the point
where it exits the roof and at least two feet higher than
any part of the roof system within 10 feet. Terminate with a
listed or approved cap. Figure 8

CONNECTING THE VENT
If more than one gas appliance is vented through a
common vent system, the vent should be increased in size
to accommodate the increased load. Consult your local
code or the tables in the latest edition of NFPA54 / ANSI.
Z223.1 for the correct size. If no local codes apply, use the
following alternate method for sizing a vent connected
to more than one appliance. The effective area of the
vent must be not less than the area of the largest vent
connection plus 50 percent of the areas of additional draft
hood outlets.
The homeowner appreciates neatness in workmanship and
the neat installation usually functions better than the slop-
py one. Double check your work to verify that all clearances
and that the vent system is installed to code or pipe manu-

8. Have all connections made at the storage tank by a
licensed Propane Gas installer.
9. Have Propane Installer check all lines, piping, and
tank.
10. The regulator on the storage tank should be set at 11
inches water column.
CHECKING THE GAS PIPING
All joints must be tested for leaks by applying pressure to
the piping system. If the test pressure is equal to or less
gas supply piping system by closing the manual gas shut-
valve must be disconnected from the gas piping system
before testing. Failure to do so may result in damage
to the pressure regulator in the gas valve resulting in
overfiring. Overfrring can result in combustion chamber
failure, property damage, bodily injury or death.
Use a mixture of soap and water or liquid detergent to
check each joint. Leaks will be indicated by bubbles forming.
Correct even the smallest leak at once. Since some soaps
may cause corrosion, or stress cracking, rinse the gas piping
exterior with water after testing to remove the soap.
WARNING: NEVER USE A MATCH, CANDLE, OPEN
FLAME OR OTHER METHOD WHICH COULD
PROVIDE A SOURCE OF IGNITION TO TEST FOR LEAKS.
TO DO SO MAY RESULT IN PROPERTY DAMAGE,
BODILY INJURY OR DEATH.
CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
When you have determined that there are no leaks in
the gas piping system you may purge the system of air.
Disconnect the pilot supply tubing from the right side of
the valve. Figure 12
Turn the knob on the gas valve to the pilot position. Press
the knob down and hold until you smell gas at the pilot
supply opening. Release the knob and tum it to the off
position. Reconnect the pilot supply tubing and check for
leaks with soap and water or liquid detergent.
