w.c.) CFM Size 4 Size 5 Modulating Gas System The second system, the Maxitrol modulating gas system, consists of a temperature selector dial, a discharge air sensor, an amplifier, and a Maxitrol 14 modulating gas valve. The two types of Maxitrol systems used are the Maxitrol Amplifier14 series or the Maxitrol 44 series. The Maxitrol 14 utilizes a discharge air sensor and modulates the Maxitrol gas valve to provide discharge air to match the selected temperature on the temperature selector. The M

Refer to Table 9 for proper nozzle size, air settings and fuel pump pressure setting based on desired firing rate. If the desired firing rate is the lower GPH: a. replace the factory installed high firing rate nozzle with one of the loose lower firing rate nozzles. b. replace the factory installed head positioning bar with the corresponding head bar that matches the lower GPH nozzle installed, see Table 9. c. change the factory air settings according to Table 9 and, d. check the oil pump pressur

i. Assure that all system radiators, piping and vents are absolutely leak tight. • When a steam boiler is installed in an existing system, ALL air vents should be replaced at the same time. This assures that the new boiler will not be compromised by existing system leaks. • If the system contains hidden supply or return piping (hidden behind walls, buried in concrete, etc.) pressure test this piping to assure there are no leaks. ii. Repair any leaks in the system. iii. Install accurate water met

Freeze Protection If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter. System Drain-Down 1. Turn the unit circuit breaker or disconnect switch to OFF. 2. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet water unions to allow water to drain. Use a Wet/Dry Vac or air pressure to remove excess water. 3. Loosely re-attach the unions. 4
