CONTROLS AND SAFETY DEVICES
This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is
against federal regulations to alter this setting or otherwise operate this wood heater in a man-
ner inconsistent with operating instructions in this manual.
Furnace Control - Your Heatmaster ss G SERIES furnace uses a factory-programed control
to maintain your water temperature by using an air damper control and draft inducer fan. The
control is located around the corner to the left of the firebox door and requires no user program-
ming or changes. The control displays the water temperature in your furnace, the damper air
percentage and any alarm messages, if set off.
Air Damper - The damper air percentage is the amount of air being drawn through the furnace
to stoke the fire. This feature keeps your furnace burn clean and hot while keeping your water
temperature in the preferred range. The damper is located beneath the firebox loading door
and is a mechanical part that opens or closes the air injection port.
Draft Inducer - The draft inducer fan is located at the rear of the furnace on the top and is used
to draw air from the air damper through the furnace. The fan should be on whenever the air
damper percentage is above 0% or when the furnace bypass is open.
Furnace Bypass Handle - Use the furnace bypass when ever the firebox loading door is open.
The bypass handle is located on the side of the furnace and opens a direct exit out of the fire-
box through the chimney when ever pushed in toward the furnace. This will allow you to check
your firebox, fuel and load your furnace without smoke spillage out of the firebox loading door.
CAUTION: Do not open any door before opening the furnace bypass. Damage to the furnace
and personal injury may result.
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.
Alarm LED Light - The LED alarm light is located above the furnace bypass handle and will
blink red if the furnace smoke by pass is open, the furnace is low on water or if the water tem-
perature is too low or too high. It is intended to warn the user of potential problems.
Cold Start Button - The button is located on the control panel in the top right corner. Press
the button to bypass the low temperature function of the control to fire the furnace from a cold
start (First firing the furnace or when the water temperature has gone low).
