User maintenance procedures
Check boiler interior piping
1. Remove boiler jacket top.
2. Visually inspect for leaks around internal piping, circulators, relief valve and other fittings.
Immediately call a qualified service technician to repair any leaks.
Have leaks fixed at once by a qualifed service technician. Continual fresh
makeup water will reduce boiler life. Minerals can build up in sections, reducing
heat transfer, overheating cast iron, and causing section failure.
Do not use
system. Severe damage to boiler and system components can occur, resulting
in possible severe personal injury, death or substantial property damage.
Check venting system
1. Visually inspect the flue gas vent piping for any signs of blockage, leakage or deterioration of
the piping. Notify your qualified service technician at once if you find any problem.
Failure to inspect the vent system as noted above and have them repaired by
a qualifed service technician can result in vent system failure, causing severe
personal injury or death.

vents with diaghragm-type expansion tanks only)
1. See Figure 1.

valve "B" slightly with the tip of a screwdriver.
3. If the air vent valve appears to be working freely and not leaking, replace cap "A", twisting all
the way on.
4. Loosen cap "A" one turn to allow vent to operate.
5. Have vent replaced if it does not operate correctly.
