Abstract

The present invention relates to a modular propane gas log burner for use in fireplaces that were originally designed as wood burning fireplaces. The present burner is designed for clean burning of propane fuel and is modular so that more than one burner can be used in combination in order to create a burner configuration for wider single-sided gas log sets, for deeper single-sided gas log sets, and for two-sided or see-through gas log sets. The burner is provided with means for adjusting the fuel-to-air ratio and for adjusting the position of the flames to allow the user to achieve realistic and clean burning flames.

Claims

1. A modular propane gas log burner comprising:

a bottom pan, a mating top burner plate attached to said bottom pan so that a burner plenum is formed between the bottom pant and the top burner plate,

a rear leg attached to said bottom pan at a back side of said bottom pan in order to hold the bottom pan and the top burner plate at an angle with a supporting surface on which the rear leg rest,

an adjustable air shutter provided between a gas delivery line and a enlarged burner gas line, said enlarged burner gas line attached to the bottom pan so that the enlarged burner gas line is in gaseous communication with the burner plenum formed between the bottom pan and the top burner plate,

said top burner plate provided with slots and openings through which gas to be burned passes to escape from the burner plenum,

an adjustable slide bar provided between the bottom pan and the top burner plate so that the slide bar is located within the burner plenum and can be adjusted forward and backward to change the gas flow with the burner plenum and thus change the location of flames produced by the gas that exits through the slots and openings provided in the top burner plate.

2. A modular propane gas log burner according to claim 1 further comprising:

locking means for reversible securing the slide bar to the top burner plate.
