Installation Clearances
(Optional separated

venting shown.)
* Recommended mounting height varies with heater input.
Heaters may be mounted at a higher level if destratification
fans are installed.
For Models UHA 150-400 venting directly from top of heater is
not applicable; For roof terminal vent, elbow duct off back of
heater is required.
Clearance to Vent: 2" (5 cm)
**31" (79 cm) minimum is necessary
for servicing.
The heater must always be installed at least 6' (1.8 m) above the floor.
The vent pipe must have clearance from combustibles by 2" (5 cm).
If installed at low levels where individuals can come in contact with hot heat exchanger components,
adequate guarding must be provided.
All distances are minimum clearance requirments for service access, airflow and safety.
