VENTILATION

OUTDOOR INSTALLATION ONLY

(See additional instructions for outdoor Power- Max units in PowerMax Appendix)

For outdoor installation with built in vent top, the heater must be placed in a suitable area on a level, noncombus- tible surface. Do not install the heater under an overhang with clearances less than 3 feet from the top of the heater. The area under an overhang must be open on three sides.

IMPORTANT!

In an outdoor installation it is important to protect your heater from water damage. Ensure water is diverted from overhanging eves with a proper gutter/ drainage system. The heater must be set on a level foundation for proper rain drainage.

Maintain minimum clearances as indicated below. Install a minimum of 4 feet below, and 4 feet horizontally from any opening to a building.

The heater should not be installed closer than 6 inches to any fences, walls or shrubs at any side or back, nor closer than 18 inches at the plumbing side. A minimum clearance of 24 inches must be maintained at the front of the heater.

IMPORTANT!

When locating the heater, consider that high winds can roll over or deflect off adjacent buildings and walls. Normally, placing the heater at least three feet from any wall will minimize downdraft.

Unusually high prevailing wind conditions and downdrafts may require the use of a stack type outdoor vent kit (available at additional cost).

NOTE

This unit shall not be operated outdoors at temperatures below 0o F. for propane and -20oF. for natural gas.
