Installation Requirements

Proper installation is critical for safe and efficient operation. Follow all local building codes and regulations.

Location: Install at least 25 feet from any structure with proper clearance from combustible materials
Foundation: Level concrete pad or gravel base required
Chimney: Minimum 15 feet height with proper clearance from roof lines
Water Connections: Use high-temperature PEX piping with proper insulation
Electrical: 120V AC power source with GFCI protection

WARNING! Installation must be performed by qualified professional. Improper installation can cause fire hazard.

First-Time Setup

Complete system commissioning before first use.

Fill water system: Check all valves open; fill slowly to prevent air locks
Pressure test: Verify system holds 20-30 PSI without leaks
Initial firing: Start with small load of dry wood; gradually increase
Temperature calibration: Set operating temperature between 160-180°F
Circulation check: Verify pump operation and heat distribution

CAUTION! Never operate with empty water system. Monitor pressure during initial heating.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No heat output	Pump failure/low water	Check pump operation; verify water level and pressure
Poor combustion	Wet wood/chimney blockage	Use dry wood; inspect and clean chimney
Water leaks	Loose fittings/gasket failure	Tighten connections; replace door gaskets
High fuel consumption	Poor insulation/air leaks	Check door seals; ensure proper wood loading
Pressure fluctuations	Air in system/expansion tank	Bleed air from system; check expansion tank pressure

Emergency Shutdown: Turn off power; close air intake; allow system to cool completely.
