Empire Comfort Systems PV-28SV50-B(N,P)-1 Clearances for Direct Vent, Locating Wall Opening

CLEARANCES FOR DIRECT VENT

1.Pick a location on a wall with a clear space in the room. In selecting a location for installation, it is necessary to provide adequate accessibility clearances for servicing and proper installation. Be sure to locate the unit close enough to a 110 VAC wall receptacle to properly power appliance.

2.When facing the front of the furnace the minimum clearances from casing to combustible construction are 0” (0 mm) on top, 0” (0 mm) on each side, recommend 4” (102 mm) on sides for servicing and 0” (0 mm) from the floor, 0” (0 mm) to rear wall and 40” (1,016 mm) from Mantis top to ceiling.

3.The minimum distance from the center of the vent cap to the nearest outside corner or obstruction is 12” (305 mm).

4.The minimum wall depth is 4” (102 mm) and the maximum is 48” (121.92 cm).

The vent terminal of a direct vent appliance, with an input of 50,000 BTU (14.6KW) per hour or less shall be located at least 9” (229 mm) from any opening through which flue gases could enter a building.

The bottom of the exhaust vent terminal and the air intake shall be located at least 12” (305 mm) above grade and must be vented outside.

WARNING: The nearest point of the vent cap should be a minimum horizontal distant of six (6) feet (1.83 m) from any pressure regulator. In case of regulator malfunction, the six (6) feet (1.83 m) distance will reduce the chance of gas entering the vent cap.

Installation on Rugs and Tile

If this appliance is to be installed directly on carpeting, tile, or other combustible material, other than wood flooring, the appliance shall be installed on a metal or wood panel extending the full width and depth of the appliance.

The base referred to above does not mean the fire-proof base as used on wood stoves. The protection is primarily for rugs that may be extremely thick and light-color tile that can discolor.
