Loading The Furnace; Controls & Safety Devices - Heatmaster G100 Operation And Maintenance Manual

Before opening any door to the furnace:
1. Push the Furnace Bypass Rod in towards the furnace. This will open the smoke bypass
so no smoke or flame exits the firebox door when you open it.
2. Crack the firebox door open to the safety catch for at least 20 seconds to allow the air
draft to build out the chimney and prevent blow back.
3. Open door slowly while standing behind the door
4. Load wood carefully using the information and diagram on the following page.
WARNING: Risk of fire:
WARNING:
- Do not operate with fuel loading or ash removal doors open.
- Do not store fuel or other combustible material within marked installation
clearances
- Inspect and clean flues and chimney regularly
CAUTION : Hot Surfaces: Keep children away. Do not touch during operation.
CAUTION :
Furnace Control - Your Heatmaster ss G SERIES furnace uses a programmable 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 above and to the left of the firebox loading door and opens a direct exit
out of the firebox 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
CAUTION :
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
