Page 12: Combustion Air For Indoor Installation
G Series Outdoor Furnaces COMBUSTION AIR Fireplaces, other furnaces, clothes dryers, exhaust fans, and other appliances all draw air from the room in which they are located. Your G Series furnace adds to that draw, making it important to ensure there is an adequate source of fresh air to offset these demands. -
Page 13: Wiring
G Series Outdoor Furnaces WIRING All wiring must conform to local codes. Use an electrical wire rated and approved for underground installations. This wiring can be placed in the same trench below the water lines. A qualified technician must perform the electrical portion of the installation. See Page 28 and 29 for the furnace wiring diagram. -

- Page 17 G Series Outdoor Furnaces DOMESTIC HOT WATER Flat plate exchanger systems used to pre heat domestic water tanks are generally more reactive to hot water demands then tube and shell systems. However tube and shell ex- changers hold up better when hard water is present. FORCED AIR FURNACE (WATER-TO-AIR EXCHANGER) The water-to-air heat exchanger must be mounted so that air blows through the fins (coils).

Page 18: Operating The Furnace
G Series Outdoor Furnaces OPERATING THE FURNACE FILLING THE FURNACE WITH WATER Your furnace has a vent pipe that protrudes through the roof which is used to fill the furnace with water. CAUTION: Do not fire furnace until it is filled with water. Allow furnace to run for 2 days and check system water levels and fittings for leaks. -
Page 19: Wood Quality, Testing And Storage
Keep in mind the diameter of wood you use. Especially with the G100, using wood that is no larger in diameter than 6” will give you a better, more even burn. For the G200 and G400 larger diameter wood can be used but do not exceed 8”. -
Page 20: Loading The Furnace
G Series Outdoor Furnaces OPERATING THE FURNACE LOADING THE FURNACE Before opening any door to the furnace: Pull the Furnace Smoke Bypass Handle towards the front of the furnace. This will open the smoke bypass so no smoke or flame exits the firebox door when you open it. -
Page 21: Operating A Gasification Furnace
G Series Outdoor Furnaces Operating a gasification furnace requires: 1. Use seasoned wood - It is always rec- ommended to use dry seasoned wood (15- 20% moisture, seasoned 1-2 years) when op- erating a gasification furnace with a minimal mix of green wood. If required to burn green or wet wood, always mix with a higher ratio of dry or seasoned wood. -
Page 22: How A Gasification Furnace Works
G Series outdoor furnaces are continuing that trend. They operate more efficiently with fewer emissions than other outdoor furnaces. The Heatmaster ss G Se- ries wood furnaces use up to 50% less wood to create the same heat. -
Page 23: Controls & Safety Devices
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. -
Page 24: Care And Maintenance
G Series Outdoor Furnaces CARE AND MAINTENANCE To obtain the high levels of performance of your furnace, certain maintenance proce- dures are required periodically . On a daily basis: Ensure that all doors are closed and sealing properly. Adjust if necessary. Check for creosote buildup in firebox and lower combustion chamber. - Page 25 G Series Outdoor Furnaces CARE AND MAINTENANCE On a seasonal basis when furnace is not in use, you will have to: Remove all ashes and excess creosote from firebox, lower combustion chamber, heat exchange tubes and chimney. Check all gasket seals to make sure they are sealing. To replace, remove the old seal and residues from the door, scuff the surface where the seal is placed with sandpaper and re-apply high temp silicone.

G Series Outdoor Furnaces TROUBLESHOOTING Troubleshooting to ensure proper burning and air flow If your furnace is not producing enough heat, is smoking while burning, there is no exhaust coming from the chimney or there is general concern on how well it is functioning you can confirm functionality using this process: Remove damper cover located below the firebox door and ensure the damper is opening the metal disc when the furnace is calling for heat and closing when the furnace is satisfied. - Page 27 5 gallon bucket and time how fast it fills up. You should be able to calculate flow rate in that line. Do this for each line coming off of the furnace to calculate furnace flow rate. Below are required flow rates for each G Series furnace: G100 - 7 GPM G200 - 16 GPM G400 - 25 GPM If the flow rate does not match what the furnace requires, make sure all lines on the furnace are being used.
- Page 28 G Series Outdoor Furnaces TROUBLESHOOTING If the furnace has shut down: 1. Check to ensure that the unit has power. 2. Check to ensure the furnace On/Off switch is in the On position. 3. Check the water temperature (furnace has a high temperature cut off of 190 de grees F and turns on again at 140 degrees).
