VENTING
Vent connectors serving Category I & Category II heaters shall not be connected into any
portion of mechanical draft systems operating under positive pressure.
This furnace is equipped with a blocked vent shut off system.
DO NOT attempt to run this furnace until a qualified service man has checked the
installation.
INSTALLATION
The installation must conform with local building codes or in the absence of local codes, the
installation must conform with the National Fuel Code, ANSI Z223.1
Your furnace has been provided with a Draft Hood. This device must be used. This
furnace also requires a blocked vent shut off device or spill switch (snap disc). The
electrical schematic shows how this device is wired into the furnace controls. This device
must be reset each time the sensor detects a venting failure. If the Blocked Vent switch
has locked the system out, contact a qualified service man before attempting to restart the
furnace.
NOTE: Negative room pressures in buildings with exhaust fans will cause the blocked vent
device to lock the gas valve out. (Heating will cease)
GENERAL RULES
1. Do not reduce the stack size anywhere in the entire vent system..
2. The stack must not be closer than 12” to any combustible material.
3. All horizontal runs must slope upwards not less than ¼” per foot from the heater
towards the vertical riser or extension.
4. All horizontal runs must be supported to prevent sagging.
The venting may be supported by steel strap or wires around the tube and tied up to
any convenient overhead support. Supports must be provided at each connection.
5. Each connection should be secured by at least three sheet metal screws. More may be
necessary depending upon installation.
6. The stack must be installed in such a manner to prevent accumulation of condensation.
7. If required, the stack must have a method of draining the condensation.
8. Use any type B flue or vent connectors. Unless local codes specify a superior type of
flue or vent connectors.
9. Venting failures can be caused by adverse weather, exhaust fans being on at the same
time as the furnace, inadequate make up air supply, lack of down-draft cap, etc.
10. Never allow less than 2’ vertical pipe for each 1’ of horizontal vent pipe.
11. Draft should never be less than .02” WC nor over .05” WC.
