Do not use automatic air vents in systems with closedtype tanks. The air will escape from the system instead of returning to the tank. s Eventually, the tank will waterlog and no longer control pressurization. The boiler relief valve will weep frequently.
TM GAS-FIRED WATER BOILER — Boiler Manual Annual startup (continued) Check ignition wiring 1. Check ignition cable electrical resistance. A good cable will have resistance between 950 and 1050 ohms. Replace if not acceptable. 2. Inspect boiler ground wire from heat exchanger access cover to ground terminal screw. 3. Verify all wiring is in good condition and securely attached. 4. Check ground continuity of wiring using continuity meter. 5. Replace ground wires if results are not satisfactory.
TM GAS-FIRED WATER BOILER — Boiler Manual Annual startup (continued) Check blower speeds 1. For installations at altitudes above 5,500 feet, make sure the control is set up for high altitude in the boiler setup menu.
