NOTE: When an existing Category I heater is removed or replaced, the original venting system may no longer be sized to properly
vent the attached appliances. The following is a list of possible causes and corrective actions.

POSSIBLE CAUSES

1. Blockage in
Vent Pipe
2. Burner is
Over Firing
3. Improper Vent System
A. Vent Too Short
B. Restriction in
Vent System
Caused by
Offsets
C. Incorrect Vent Pipe
4. Loose Connections

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.

CORRECTIVE ACTION

1. A) Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc.
B) Check that the vent cap is properly installed, not shoved too far down on the vent pipe.
2. A) Check the manifold pressure.
B) Check the rate
NOTE: This appliance was orificed for elevations up to 2,000 feet. When
installed at higher elevations refer to orifice chart (on page 9) in main burner
orifice section of instructions for proper orifice size and re-orifice accordingly.
3. Correct Vent System
A) The vent should not terminate less than 5 feet above the drafthood connection. A gas vent
extending through an exterior wall shall not terminate adjacent to the wall or below eaves or
parapets. Also, the top of the vent must be at least 2 feet above all obstacles within a 10 feet
radius, including the roof. See Figure A (on page 5).
B) All type "B" vent shall extend 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 the venting action to begin before any restriction is encountered.
C) Use listed "B" type vent pipe. Do not use transite or any other type of ceramic pipe for
venting. Do not use single wall pipe for vent or vent connector.
4. Check the connection on both the switch and the gas valve. Tighten if necessary.
VENTING
6) Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat so
appliance is operating continuously.
7) Test for spillage from draft hood equipped appliances at
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.
