All Models
Models GHE80SU-200(A) & GHE80SU-300(A) are limited to an altitude of 8000 ft, while all other models are limited to 8999 ft.
Model GHE119SU-500(A) if installed above 5000 ft, refer to "Gas Valve Instructions" for adjustments.
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.
Venting Configurations are the Same for SS Models:
3 inch concentric vent can only be used with 3 inch rigid piping.
4 inch concentric vent can only be used with 4 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.
Note: For Horizontal Power Direct Vent configurations, GHE119SS/SU models will need to have a 45 degree elbow
on the intake and a 90 degree elbow on the exhaust, if they are on the same plane.

GHE80 and GHE 100 Models
GHE119-500
Models GHE80SU-200(A) & GHE80SU-300(A) are limited to an altitude of 8000 ft, while all other models are limited to 8999 ft.
NOTE: Units naturally de-rate as vent length is extended from minimum vent. De-rate also occurs when
reducing the diameter of the vent from the default size (GHE80/100 default is 3", GHE119 default is 4").
