2. Connect to chimney: Install 6-inch flue pipe with proper slope and connections.
3. Install ductwork: Connect supply and return air ducts according to local codes.
4. Electrical connection: Wire blower motor to appropriate power supply.
5. Test operation: Verify all components function properly before regular use.

WARNING! Installation must comply with local building codes and NFPA standards. Professional installation recommended.

First-Time Setup

Prepare furnace for initial use and establish proper operation.

1. Inspect firebox: Ensure clean and free of debris.
2. Check gaskets: Verify door gaskets are properly seated.
3. Test draft: Confirm adequate chimney draft before lighting.
4. Seasonal adjustment: Set thermostatic control for current weather conditions.
5. Cure firebrick: Follow initial firing procedure to condition firebrick.

CAUTION! Never use flammable liquids to start fire. Use only dry, seasoned wood.

Controls and Settings

Primary controls include draft control, blower switch, and door latches.

Draft Control: Adjusts primary air intake for burn rate control. Higher settings for faster burn, lower for longer burn times.

Blower Control: Manual or thermostat-controlled operation. Adjust speed for desired air flow and heat distribution.

Door Latches: Ensure tight seal for proper combustion. Lubricate periodically with high-temperature lubricant.

Connecting to Ductwork

Proper ductwork installation is critical for efficient heat distribution.

1. Size ducts appropriately for furnace capacity and building layout.
2. Install dampers to balance heat distribution throughout building.
3. Ensure proper return air configuration for efficient operation.
4. Seal all duct connections to prevent heat loss.
5. Install cleanout access points for maintenance.

Tip: Consult HVAC professional for optimal ductwork design and installation.

Operating Procedures

Proper operation ensures efficiency and safety.

1. Loading: Place wood toward back of firebox, leaving air space between pieces.
2. Starting fire: Use kindling and fire starters; never use gasoline or lighter fluid.
3. Adjusting draft: Set control based on desired heat output and burn time.
4. Adding wood: Open door slowly to prevent smoke spillage.
5. Ash removal: Empty ash pan when 1-2 inches accumulate.
6. Overnight operation: Load fully and reduce draft for extended burn.

WARNING! Always wear heat-resistant gloves when handling furnace components.

Safety Features

Overheat protection: Automatic shutdown if temperatures exceed safe limits. Door safety: Latches prevent accidental opening during operation. Chimney monitoring: Draft indicator shows proper venting operation.

Maintenance & Cleaning

Regular maintenance ensures optimal performance and safety.

1. Daily: Empty ash pan as needed
2. Weekly: Inspect door gaskets and clean glass
3. Monthly: Clean heat exchanger surfaces
4. Seasonally: Inspect and clean chimney and flue
5. Annually: Professional inspection recommended

CAUTION! Allow furnace to cool completely before performing maintenance.
