COOLING SYSTEM FOR GAS FIREPLACE

摘要

A power vented fireplace uses a single air inlet to pressurize a staging area from where air is distributed along a passageway between viewing panels to cool them as well as into the combustion chamber as a supply of combustion air. A partial restriction at an inlet to the passageway ensures that sufficient air is directed into the combustion chamber. The inlet to passageway may be adjustable to vary the extent of the restriction. Pressure differential switches may be used to ensure balanced operation of the fireplace.

主权项

1. A power vented gas fireplace having a combustion chamber with a first transparent panel for viewing into said chamber and a second transparent panel spaced from said first panel and defining a passageway between said first and second panels, said fireplace having a single source of inlet air, said fireplace directing inlet air into a staging area that is pressurized by an air inlet fan and distributing said inlet air from said staging area into said combustion chamber through small openings between said staging area and said combustion chamber io and into said passageway through a passageway inlet that presents a partial restriction to air flow into said passageway.
