-Regulator Installation Example (Liquid Propane)-
1. Gas Appliance Shutoff - required to shutoff the gas supply to the boiler if the need for service
or repair arises.
2. Drip Leg - a plumbing conguration that is used to remove debris from the gas line before it
enters the boiler. A drip leg consists of a black iron T tting, a straight Black iron pipe (about 3-4”)
and a cap.
3. Flexible Gas Line - the regulator should be a minimum of 3’ from the boiler. The exible gas line
is an ideal solution, it reduces space and helps with alignment.
4. Line/Appliance Regulator - needed to deliver the precise gas pressure the micro-boiler needs.
It will drop the second stage regulator's 2 psi pressure down to inches of W.C.
5. Second stage regulator - brings gas pressure down to either 2 psi. or inches of W.C. The
micro-boiler operates on inches of W.C.(See Specs)
6. Propane Tank - gas pressures varies between 10 psi and 200 psi.
7. First stage regulator - brings tank gas pressure down to 10 psi. output, to high for the boiler.
8. Safety relief valve - relieves pressure in case the tank pressure build past the design
parameters.
9. Tank shutoff Valve - this valve will shut the supply to the whole house / system off.
10. Fuel Gauge - indicates the level of fuel in the tank.
