Installation
Venting Configurations are the Same for SS Models:
All power direct vent models can use 3 in. or 4 in. concentric venting the above vent lengths.
3 inch concentric vent can only be used with 3 inch rigid piping.
4 inch concentric vent can only be used with 3 inch rigid piping.
DO NOT mismatch concentric vent terminations with different rigid piping as it may cause the heater to mal-
function or cause a lock-out condition.
DO NOT use 2 inch rigid venting with concentric vent terminations.
DO NOT use 6 inch rigid venting with concentric vent terminations.

TABLE 2. POWER DIRECT VENTING LENGTHS
Models GHE80SU-200(A) & GHE80SU-300(A) are limited to an altitude of 8000 ft, while all other models are limited to
8999 ft.
Models GHE80SU-200(A) & GHE80SU-300(A) are limited to an altitude of 8000 ft, while all other models are limited to
8999 ft.
For each 90° Elbow, reduce pipe length by five (5) feet.
For each 45° Elbow, reduce pipe length by two and a half (2.5) feet.
Note: Vent pipe size should not be mixed for venting these units.
Use same diameter pipe for all venting of the unit.
