INSTALLATION REQUIREMENTS
Failure to install, maintain and/or operate the Power Vent in accordance with manufacturerʼs instructions
may result in conditions which can produce bodily injury and property damage.
The equipment must be installed by a qualified installer in accordance with all local codes, or, in the
absence of local codes, with the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and the
National Electrical Code, ANSI/NFPA 70. In Canada, installations must conform to CAN/CSA B149.1 and to the
latest Canadian Electrical Code Part 1.
Disconnect power supply when making wiring connections or when working around the fan blade and
motor. Failure to do so may result in severe personal injury and equipment damage.
Make certain the power source is adequate for the fan motor requirements. Do not add the Power Vent
to a circuit where the total load is unknown.

VENTING
The D-2 Power Vent operates with a positive vent static pressure and with a vent gas temperature that prevents
excessive condensate production in the vent, and as such, is a CATEGORY III appliance.
The total length of horizontal run shall not exceed an equivalent length of 100 ft including the termination cap.
For all cases, each 90° elbow reduces the maximum horizontal vent run by 10 ft and each 45° elbow reduces
the run by 5 ft. The vent must be installed properly to prevent the flue gas leakage within the heater. The vent
pipe must be suitable for use with Category III Appliances which have flue gas temperatures of less than 400°F.
Care must be taken during the assembly to ensure that all joints are properly sealed.
For appliances installed in extremely cold climates, it is recommended that:
a) The vent be installed with a slight upward slope of not more than 1/4” per foot of horizontal run to the
vent terminal. In this case, an approved condensation trap must be installed per applicable codes.
b) The vent be insulated through the length of the horizontal run.
The exit terminal of the D-2 Power Vent shall not be less than 7 ft above grade where located adjacent to public walkways. It must also be at least 3 ft above any forced air inlet located within a 10 ft radius.

V/BK
V/W
On call for heat, the PC board will go through its safety chain (water pressure switch, high limit 1 & 2, roll-out,
etc.). When the safety chain is closed, the IID pilot will begin to spark and the pilot gas valve will open. A flame
will be lit at the pilot assembly. When an acceptable signal is sent back to the PC board, proving the rectification, the D-2 Power Vent blower will start. When the blower comes up to speed, a draft proving switch will close
o allow the main gas valve on the heater to open. Note: On Low NOx units, the main gas valve & combustion
t
blower will turn on simultaneously. A heater with a D-2 Power Vent will continue to operate until call for heat is
satisfied.
DRAFT-PROVING SWITCH
The draft-proving switch ensures that the blower is operating. Once the D-2 Power Vent is wired to the heater,
the switch does not allow the PC board to open the main gas valve, unless it is closed.
WIRING
The D-2 Power Vent includes a wire harness which provides quick connections with the respective controls in
the appliance control box. The harness is of sufficient length to fit the unit for which it is sized.
Reference the connection diagrams on pages 15 & 16 or the wiring diagrams on pages 17 & 18 for actual connections.
