Ultra boilers are shipped ready to fire
natural gas ONLY. Exception: The Ultra-

DHW (if used) per Ultra Control Supplement?
❏ Tested additional field-installed controls — If boiler
has a low water cutoff, additional high limit or other
controls, tested for operation as outlined by
manufacturer? (Boiler should be operating and

system temperature requirements? Adjusted
balancing valves and controls to provide design
temperature to system?
❏ For multiple zones, adjusted for correct flow in each

manometer to gas valve ahead of boiler? (Gas
pressure must be at least 5 inches w.c. for natural
gas, and 4 inches w.c. for propane, with boiler
operating at high fire, and no more than 13 inches
w.c. with boiler operating or boiler off.)
❏ Observed several operating cycles for proper
