C. MONTHLY DURING HEATING SEASON
1.Remove jacket front and top panels and check for piping leaks around relief valve and other fittings. If found, contact a qualified service agency to repair. DO NOT use stop leak compounds.
2.Test relief valve. Refer to valve manufacturers instructions packaged with relief valve.
3.Visually inspect venting and air intake system for proper function, deterioration, or leakage. If the vent or air intake show any signs of deterioration or leakage, contact a qualified service agency to repair or replace them immediately and to insure proper reassembly and resealing of the vent and air intake system.
4.Visually inspect the clear vinyl condensate lines and the PVC condensate drain pipe for proper operation, leakage, and deterioration. If the condensate lines or drain pipe show any signs of blockage, leakage, or deterioration contact a qualified service agency to clean, repair, or replace them immediately.
5.Check the air baffle located inside 1 1/2"x 2" flexible coupling, clean it if necessary and make sure to put it back. Refer to repair parts diagram, mixer and pressure switch assembly.
D.PERIODICALLY DURING HEATING SEASON
1.Where low water cut offs are used, a periodic inspection of the low water cut off is necessary, including flushing of float type devices. Refer to low water cut off manufacturer’s specific instructions.
E.END OF EACH HEATING SEASON - ANNUAL SHUTDOWN PROCEDUR
1.Follow instructions “TO TURN OFF GAS TO APPLIANCE”.
2.If heating system is to remain out of service during freezing weather, and does not contain antifreeze, drain system completely. If boiler will be exposed to freezing temperatures, drain condensate lines. Otherwise, do not drain system or boiler.
F.ANNUAL EXAMINATION AND CLEANING OF BOILER COMPONENTS
The following service procedures must be performed only by a qualified service agency. Boiler owner should not attempt these procedures.
1.Before Servicing, turn off electrical power to boiler at service switch. Close manual gas valve to turn off gas supply to boiler.
2.Cleaning Flue passages between boiler sections.
a.Any buildup of sediment or aluminum oxide (white powdery or flaky substance) in the flue passages must be cleaned as follows:
b.Remove jacket front and top panels. Disconnect condensate drain line from the barbed fitting on the bottom of the boiler. Keep the open end of the drain line above the water level in the condensate trap to prevent the trap from draining. Disconnect pressure switch hose from barbed fitting on gas valve. Disconnect 1½ x 2” flexible coupling from air inlet. Disconnect air
