33 CONTR OLS Ignition Control Module The interrupted proved ignition device conserves ener- gy . When additional heat is needed, the combustion air blower starts to purge all air from the combustion chamber for about 15 seconds.
34 Lo w Wa ter Cut Of f (Optional) The low water cut off automatically shuts down the burner whenever water level drops below the level of the sensing probe. A 3-second time delay prevents premature lockout due to temporary conditions such as power fluctuations or air pockets.

36 PRE-ST ART -UP Filling System-Heating Hea ter s Fill system with water . Purge all air from the system using purge valve sequence. After system is purged of air , lower system pressure. Open valves for normal system operation, fill system through feed pressure.
37 Attach Manometers to Measur e Pressur es • Attach 24" scale manometer to the first main gas shut-off valve pressure tapping. • Attach one 12" scale manometer to the manifold gas pressure tapping.
38 F ollo w-Up • Safety checks must be recorded as performed. • T urn unit on. After main burner ignition: • Check Manometer for proper reading. • Cycle unit several times and recheck readings • Re-analyze with unit running record or print results.
39 8. T urn on all electric power to the appliance. 9. Set thermostat to desired setting. The appliance will operate. The igniter will glow after the pre- purge time delay (15 seconds). After igniter reaches temperature (45 seconds) the main valve will open.
40 Monthly: 1. Check for piping leaks around circulators, mixing valves, relief valves, and other fittings. If found, repair at once. DO NOT use petroleum-based stop leak compounds. 2. Visually inspect burner flame. 3. Visually inspect venting system for proper func- tion, deterioration or leakage.
