2) Install the Inlet Air Pipe (field supplied) - Install the inlet air pipe from the

outside terminal to within a maximum of three feet (.9M) of the burner/con-

trol box. If the inlet air pipe passes through moisture-laden air, insulation or

double-wall tubing may be needed to prevent condensation on the outside

of the pipe. Provide adequate support.

3) Attach the Combustion Air Inlet Cover (FIGURE 3) - Align the hex huts

on the combustion air inlet side of the burner/control box with the holes in

the sheetmetal drill template. Using the outer four holes in the template,

mark and drill four 7/64” diameter holes for attaching the air inlet cover.

Attach the air inlet cover using the screws provided.

4) Install Expandable Pipe - Use one clamp to attach the expandable pipe to

the air inlet cover. Use the other to attach the expandable pipe to the field-

Installation

Instructions

WARNING: If

the heater is

installed, turn

off the gas and

disconnect

the electric

before installing

the optional

combustion air

inlet kit.

Read all instructions before proceeding; do steps in the order that

best suits the installation.

WARNING: This outside air kit is to be installed by a qualified

service person in accordance with these instructions and

in compliance with all codes and requirements of authori-

ties having jurisdiction. The qualified agency performing this

work assumes responsibility for this installation.

If the inlet cap is located adjacent to the exhaust terminal, the terminals

must be separated by a minimum distance of three feet (.9M). The only

exception is when the air inlet is located directly below a horizontal vent

cap. The required clearance between an air inlet terminal located directly

below the vent cap is 18” (457mm).

NOTE: The vent and the fresh air

intake may be installed in different pressure zones.
