Auto feeder of the Combination boiler
Make sure the pump drain plug and the DHW cold water inlet filter have been
inserted and that the drain coke inside the unit are closed.
Slowly open the water supply valve on the inlet to the unit. If there is no valve at the
combination boiler, turn on the water supply at the water meter slowly.
Inspect and make sure there is no water leaking.
The combination boiler has an automatic feeder to fill water to the space heating
side. It will fill automatically and stop. Please check the manual air release to make
sure water filled properly.
Once all of the air has been bled out of the hot water lines, close all hot water
faucets.
Turn power on to the unit.
Open the gas valve.
Open a hot water faucet to test for normal operation; the unit should fire and operate
normally.
