Extension Kit Installation

Both the exhaust line and air intake hose are

supported by clamps which are attached to the wall.

A wall fixture can be used to offset the clamp from the

wall. Use Screw B to attach the wall fixture to the

wall. If the wall fixture is not used then use Screw A

and the nut to attach the clamp to the wall.

The air intake hose should always be underneath the

exhaust line so that in case the air intake hose sags it

will not come into contact with the exhaust line.

The exhaust line is connected between the bent pipe

at the rear of the heater and the exhaust port on the

flue manifold.

Installing the Exhaust Line

To connect exhaust pipes with other straight pipes or

bends, fit the male end into the female end. Use pipe

stopper A to clamp the connection.

Use pipe stopper B to fix the length on the adjustable

exhaust pipes. Do not extend these pipes beyond the

red line.

Do not cut the exhaust pipe. Use the adjustable

pipes if necessary.

To bend the elbow, insert exhaust pipes into both

ends for additional leverage. Bend to desired angle.

Do not straighten the bent pipe attached to the

appliance.

Connecting the Air Intake Hose

The air intake hose is connected between the air

connection at the rear of the heater and the air intake

port on the flue manifold.

Push the air intake hose onto the flue manifold and

secure with the plastic tie for air inlet.

Join air intake hoses by screwing the hose joint half of

its length into the air intake hose and then screwing

another air intake hose into the hose joint.

The lengths of the air intake hose and the exhaust

pipe must be the same in order for the appliance to

operate properly. The hose can be cut to the required

length. Deburr all rough edges. Do not cut the hose

attached to the appliance.

Support the air intake hose with pipe clamps.
