SPECIAL NOTES

a) You may use up to three HEVK-5 Kits for a total of 15’ vent extension with two additional elbows. DO NOT

EXTEND VENT BEYOND 15’ OR USE MORE THAN THREE TOTAL ELBOWS (one elbow comes with the b) c) heater).

To connect two vent kits together use P/N 72532 2”x3” steel coupling. Secure with 2” hose clamps.

If you are using one, two, or three kits, after installation is complete you will discard 2 P/N 72593 hose clamps and one P/N 72532 steel coupling.

d) e) f)

If you need to make a 90E offset you will need to order P/N HEEL-1 90E Elbow Kit. Two offsets require two kits.

If complete vent extension is horizontal, pipes may be sloped down slightly to allow any condensate to drain through the exhaust pipe to the outside. DO NOT ALLOW TO DRAIN ONTO WALKWAY. If any part of vent extension is vertical or local codes do not allow draining of condensate to outside you must add P/N 18900

Condensate Kit.

For cosmetic purposes, the addition of the HEVK-5 Kit can be enclosed by adding a HEVE-5 Vent Enclosure Kit.

To completely enclose the HEVK-5 Kit one HEVE-5 will be needed for each HEVK-5 used.

MAINTENANCE INSTRUCTIONS

For proper and safe operation keep furnace and furnace area clean. At regular intervals turn control valve to off, let cool and clean inside control and heat exchanger compartment. To clean front panel use only a damp cloth, do not use any kind of solvent or cleaning fluid that could leave a residue to burn or give off fumes when furnace is turned on.

Have the furnace checked, cleaned, and repaired by a qualified service technician. Check venting system, and burner operation prior to use each year.

Follow a regular service and maintenance schedule for safe and efficient operation.

Do not obstruct combustion and ventilation air. Examine the venting system as a routine part of the safety performance check on an annual basis.

If the heat exchanger is removed, check the heat exchanger intake gasket and draft inducer gasket and replace if there is any sign of damage. Be sure all gaskets are in place when the heat exchanger is replaced.

Failure to replace any gasket that has been damaged may result in property damage, personal injury or loss of life.

Oil the bearings of the fan motor every 6 months with S.A.E. 20 oil.
