Step 4 MASCOT II START UP
Before starting, make sure the installation of the boiler is in FULL compliance with the installation manual
and all local codes.
Confirm that the system is properly filled with water and both the boiler and system are purged of all air.
***A combustion analyzer and manometer is required for set up.***
If using outdoor reset, disconnect the outdoor sensor wires from terminals 5 & 6 during the start up.
• Shut off the gas supply.
Using a small screwdriver, loosen the inlet set screw.
Attach a hose from the manometer to the inlet test port.
Turn on the gas supply.
Measure the inlet static gas pressure.
Do not remove the manometer. You will need to measure the gas
supply pressure with the boiler running at high fire.
