Operation

Attach Handles

The fallaway handles are used to open and close the 
front doors. Remove after each use so they will not get 
hot. Keep in convenient location for each use. (Fig. 26)
Assemble the primary air control and damper handles 
by passing the 3

³⁄₈

” screw through the ceramic shaft 

and into the bright metal hub. Tighten carefully until 
snug. Do not overtighten. Ceramic handle could crack.

EWF36A Controls 

Three controls regulate the performance of the 
EWF36A fireplace:  A primary air control supplies oxy-
gen for the fire, the damper directs air flow within the 
fireplace and a variable-speed fan control, or rheostat, 
regulates the warm air flow into the room. (Fig. 28)

Primary Air Control

A single air control regulates the amount of heat the fire 
will produce and how long it will burn.

The 

primary air control

 is located in the upper left 

corner of the unit.  (Fig. 26) It is the primary source of 
air for starting, maintaining, and reviving the fire.
Generally, more air entering the fireplace makes the fire 
burn hotter and faster, while less air prolongs the burn.
The air supply is open to the maximum when the control 
lever is rotated clockwise, and closed when rotated 
counterclockwise.  To vary the burn rate, adjust the con-
trol to the desired position in between these extremes; 
opening the primary air control makes the unit burn 
hotter. Closing the control slows the unit down. You may 
adjust to any position you desire.

The Damper

The damper directs air flow within the fireplace.

The 

damper

 is operated by moving the lever located 

in the upper right corner of the unit. It has two posi-
tions: Open to start or revive the fire and closed, for 
normal operation and to control burn rate. The damper 
is open when the lever is fully rotated counterclockwise 
and pulled out and closed when pushed in. When the 
damper is in the open position, with the lever pulled out, 
and rotated fully in the clockwise direction, the handle 
can ‘telescope’ back without closing the damper or any 
damper movement. There are no intermediate settings 
for the damper.

NOTE:

 Full clockwise or counterclockwise movement of 

the damper handle is approximately 50°.

NOTE:

 Always open the damper before opening the 

doors. Close damper to set burn rate.
