Firebox Door Handle
Principles of the Firebox Door Handle
Fastened to the firebox door, the handle provides a secure method of controlling the
opening and closing of the firebox door. By opening the firebox door, (only until the door
handle hits the second stage of the safety latch), gives a space for fresh air to enter the
firebox without the risk of a “flash back.” The firebox door handle is also designed to “stick”
to the
firebox door
handle holder
on the outer door. This procedure prevents either of the
doors closing while the Heatmor
TM
is being loaded with coal.
ABSOLUTELY NO FIRE IN THE FIREBOX WHEN
PERFORMING THIS PROCESS.DO NOT PERFORM THIS
PROCESS WHEN UNIT HTF TEMPERATURE IS UNSAFE.
ALWAYS WEAR PROPER PERSONAL PROTECTIVE
EQUIPMENT WHEN WORKING WITH HTF AND CHEMICALS.
Maintenance / Result
To maintain the door handle, ensure the handle closes and opens fairly easily. If the handle
closes too hard, it will be hard to open and close the door. If the closure is too loose, it will
be harder to obtain a perfect seal around the door. If you do not have a firm seal, you could
potentially create an air leak resulting in further complications. Refer to “Checking for Air
Leaks” for further details or contact your local dealer. You can adjust the two bolts on the
latch for correct closure.
