Main Burner Flame
A properly adjusted main burner flame will produce a tight blue flame pattern about 1/2 inch tall from the burner’s surface, Figure 21. A yellow floating or tall stringy flame is not normal and must be corrected.
WARNING:Yellow, floating flames indicate a lack of combustion air. DO NOT operate the boiler until the problem is solved or severe personal injury or death may occur!

Thermostat Adjustment
Set the heat anticipator to 1.1 amps when controlling the boiler directly. For zoned systems set the heat anticipator to match the amp draw of the zone valves or pump relays.
BOILER MAINTENANCE
The boiler should be cleaned and inspected once a year, before each heating season. Refer to Figures 22 for component identification
CAUTION: Servicing, inspection and adjustment must be done by a trained technician in accordance with all applicable local and national codes. Improper servicing or adjustment could damage the boiler!
Control Panel
Use a soft brush and/or a vacuum cleaner to ensure that the electrical components are free from dust or deposits that would impair the boiler's performance.
Air Filter
1.Remove the front jacket panel.
2.Remove the filter box cover and filter.
3.Wash the filter in warm water. Shake out all excess moisture before reinstalling.
Burner Box Removal & Replacement
CAUTION: The burner box should not be removed! Careless handling can damage the burner.
WARNING: The ceramic combusiton chamber in the burner box and its gasket contain crystalline silica. Wear a tightly fitted dust mask when servicing the burner and gently handle the burner and its gasket to prevent inhalation of airborne fibers. Crystalline silica fibers have been identified as carcinogenic, or possibly carcinogenic when inhaled.
If you suspect a problem within the burner assembly, please contact a local manufacturer representative.
Condensate System
Ensure that the condensate removal system is sound and working properly.
Vent System
The entire vent system must be thoroughly inspected for any signs of blockage, corrosion or leaks. Immediately replace any unsound vent system piping. Remove any foreign matter in or near the vent terminal or around the boiler that might obstruct the flow of combustion and ventilation air.
Blower Motor
Every 3 to 6 months, lubricate the inducer motor using 2 drops of 20W non detergent motor oil in each oil port.
Low Water Cutoff
If the boiler has been equipped with a low water cut- off device, follow the manufacturer's instructions for cleaning and to confirm proper operation
Relief Valve
The relief valve should vent water when the test lever is lifted. It should not weep or discharge water at normal system pressure. NEVER try to clean or repair the relief valve! If the valve fails replace it!
Aquastat High Limit
The aquastat high limit controls the maximum water temperature in the boiler. It is adjustable from 140°F (60°C) to 220°F (104°C). If the water temperature reaches the set temperature before the demand for heat has been met, the aquastat high limit should shut the burners off. The outlet water temperature should never exceed 220°F (104°C). If the aquastat high limit fails to function properly replace it.
