Section 13 - Compressed Air Installation
Compressed Air Supply Installation
1. Install an air pressure supply line connection to the air filter/regulator.
2. The air supply source must be capable of producing 1.0 CFM @ 100 PSI.
3. Install a shut off valve in the air supply line for service.
4. Install a primary air filter/regulator with a gauge (capable of reading line pressure) in the air supply line prior to
the air filter/regulator mounted on the furnace. THE PRIMARY AIR FILTER/REGULATOR IS NOT SUPPLIED WITH
THE BOILER.
5. If the primary air regulator does not have a filter with a bowl, a condensate drain leg must be installed in the air sup-
ply line.
6. Install a quick disconnect at the air filter/regulator on the boiler for service.
7. For the ease of installation install a flexible air line (.250 I.D. minimum) from the quick disconnect to the primary air
regulator.
8. The air supply line must be pitched upward from the primary regulator to the boiler to prevent condensation from
entering your burner.
9. Open all air shut off valves, and set the primary air regulator at 30 PSI.
10. Set the secondary air filter/regulator to 15 PSI.
