Check primary and gas piping
1. If gas odor, or leak is detected, immediately shut down the unit and call a qualified service technician;
2. Visually inspect for leaks around the internal boiler water connections and around the heat exchanger. Visually inspect the
external system piping, circulators, and system components and fittings. Immediately call a qualified service technician to
repair any leaks.
WARNING
Have leaks fixed at once by a qualified service technician. Failure to comply could result in severe personal injury,
death or substantial property damage.
Operate Pressure Relief Valve
1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of
scalding from hot water.
WARNING
To avoid water damage or scalding due to valve operation, a discharge line must be connected to the relief valve outlet
and directed to a safe place of disposal. This discharge line must be installed by a qualified service technician or
heating / plumbing installer in accordance with the Boiler installation manual. The discharge line must be terminated
so as to eliminate the possibility of severe burns or property damage should the valve discharges.
1. Read the pressure gauge to ensure the system is pressurized (Min. 7.25 psi / 0.50 bar and Max is 25.50 psi / 1.80 bar). Lift
the relief valve top lever slightly, allowing water to relieve through the valve and discharge piping;
2. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe to ensure
that the valve does not weep after the line has had time to drain. If the valve weeps, lift the lever again to attempt to clean
the valve seat. If the valve does not properly seat and continues to weep afterwards, contact a qualified service technician
to inspect the valve and system;
3. If the water does not flow from the valve when you lift the lever completely, the valve or discharge line may be blocked.
Immediately shut the unit down and call a qualified service technician to inspect the valve and system.
