You should allow 20 minutes to fill the tank and generate
steam.

blowdown valve, emptying the boiler tank and releasing
water and steam to the drain. This should be done at least
once daily to remove sediment, lime, or scale.

Should read 9 -11 psi during operation; 0 psi during
shutdown.
Observe level of water in the boiler and water quality.
Murkiness in the water indicates inadequate water quality;
the owner must supply proper water to the boiler (see page
4, Water Quality Statement).
- While ON, briefly open the water level control daily to
remove any sediment that might accumulate.
- This valve will release (pop off) if the boiler has too much
pressure. Once a week, this valve should be tripped
during operation to make sure it functions properly.
