Care And Maintenance - Heatmaster C-150 Operation And Maintenance Manual

firebox. It can also be removed by bending the tabs
on the front right and left corners down and sliding it
forward. The top bypass divider can slide completely
out which will give plenty of room to drag any ash
forward and out the top clean-out door (there is
no divider in the C800 model). Be sure to replace
it right-side up as it will not allow airflow through
upside down. If wet creosote accumulates in the top
of the chimney the burn rate is probably too slow and
adjustments in loading, burn times or burn rate may
be necessary to prevent the furnace airways from
becoming blocked.
CONTROLS AND SAFETY DEVICES
Furnace Control - Your Heatmaster
uses a factory-programed aqua stat control to
maintain your water temperature by lifting a solenoid
to open the air way and engaging the draft fan. The
control is located around the corner to the left of the
firebox door and displays the water temperature
in your furnace. Programming and troubleshooting
instructions can be found on page 20 of this manual.
To obtain the high levels of performance of your
furnace, certain maintenance procedures are required
periodically to avoid soot, creosote and ash buildup.
On a daily basis you need to:
• Check for ash and creosote buildup until
experience shows how often cleaning is necessary.
• Remove ashes.
• Ensure that the door gasket is sealing properly.
• Ensure that door and ash drawer are closed and
sealing properly.
• Check water level.
• Check for sparks or coals that may have fallen
from the furnace and make sure they are safely
disposed of.
On a weekly basis you need to
• Check for ash and creosote build up in the bypass
trough, top heat exchange chamber and chimney.
Fly ash should be removed to allow free airflow
through the furnace. An ash choked furnace flue
will reduce the burn rate and create poor heat
transfer.

CARE AND MAINTENANCE

Solenoid - The solenoid is located beside the black
metal airbox mounted on the rear of the furnace
and is a mechanical part that opens or closes the
air injection port. The solenoid should lift when the
furnace is calling for heat and lower when the furnace
has reached its desired temperature.
Draft Fan - The draft fan is located at the rear of the
furnace on top of the black metal airbox and is used
to inject air in to the furnace. The fan should be on
whenever the furnace is calling for heat.
Timer – The timer is located in the rear of the furnace
near the lead in power box. It can be set using the
instructions on page 21 of this manual to turn the
draft fan on in set intervals to keep the coal bed alive
during times of idle.
High Limit Switch - The high limit cut off switch is
used to ensure the furnace does not cause damage
via runaway fire. It acts as a safety switch by cutting
power off to the fan if the water temperature rises
above 190° F.
• Removal of creosote may be necessary in mild
weather. Burning your furnace with a larger
differential at higher temperatures means less
creosote buildup.
On a seasonal basis when furnace is not in use, you
will have to:
• Remove all ashes and excess creosote.
• Inspect the firebox for leaks and any other possible
problems.
• Clean out bypass trough and chimney.
• Cover chimney and crack open the ash pan door
enough to allow air movement and reduction of
condensation within the fire drum.
• Have your water treatment tested and adjusted to
manufacturer's specifications. See page 5 for exact
specifications.
• Change your water filter cartridge and inspect all
of your system for leaks.
• Tighten your firebox door by adjusting the hinges
on each side of the door.
