When your furnace blower is not running, the 10 x 20 inch door will be open. With the door in the open position, your furnace will be operating as a GRAVITY TYPE SYSTEM. Cool basement air can now enter the 10 x 20 inch door and flow into your furnace. The air will be heated by your Charmaster furnace and flow out your hot air registers, heating your home.

When your home is heated by gravity air flow, the blower motor will start less often and run for shorter periods of time. This saves you money on your monthly electric bill and provides more even heat.

During an electrical power outage, the 10 x 20 inch door will automatically open, and the combustion air draft door will close. Your furnace would be on gravity heat during a power outage - cooling your furnace and heating your home.

Standard 10 x 20 inch furnace filters are used in this unit for complete air filtration.

Cold Air Return Package
The cold air return can greatly increase the efficiency of your wood furnace and help in the circulation of heat in your home. Most basement heating installations would include a cold air return. It is custom made to fit a Chalet, Charmaster or Charmaster II furnace, and includes an air filter. This can be installed on either side of the furnace.

Safety Heat Dump
The Safety Heat Dump is mounted on any side of your hot air plenum. A 10 x 20 inch door is held closed by a spring and fusible link. This door remains closed as long as the furnace blower cycles, and the furnace heat is being forced out through your hot air duct work system.

Should your home experience an ELECTRICAL POWER OUTAGE, the furnace blower would not function. During that time, your plenum temperature may reach 280 degrees or more. At that time a fusible link will melt in the Safety Heat Dump, which allows the 10 x 20 inch door to open. This will allow the excess hot air to escape safely into your basement. This safety system, which is exclusive with Charmaster, prevents your duct work from overheating. Three fusible links are include with every Safety Heat Dump, and replacements are available from Charmaster.
