Check-out/startup verification

❏Boiler and heat distribution units filled with water?

❏Water chemistry verified per page 23?

❏Automatic air vents, if used, open one full turn?

❏Air purged from system?

❏Air purged from gas piping? Piping checked for leaks?

❏Propane orifice installed for propane firing and propane conversion label affixed to jacket?

Ultra boilers are shipped ready to fire natural gas ONLY. Exception: The Ultra- 80LP is factory-equipped to fire propane. You must install the propane orifice or conversion kit (Ultra-80NG) if the boiler will be connected to propane. See page 9. Failure to comply could result in severe personal injury, death or substantial property damage.

❏Thermostat circuit wiring checked to ensure there are no stray voltages per page 24, “Check Thermostat Wires?”

❏Followed Operating Instructions in Ultra Control Supplement?

❏Burner flame and combustion verified per page 25?

❏Verified control operation for space heating and 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 should go off when controls are tested. Verify controls cause soft lockout or hard lockout as desired.)

❏Set additional field-installed limit control(s) to system temperature requirements? Adjusted balancing valves and controls to provide design temperature to system?

❏For multiple zones, adjusted for correct flow in each zone?

❏Verified thermostat heat anticipator (if available) set properly? Refer to Ultra Control Supplement.

❏Cycled boiler with thermostat (and with DHW aquastat, if installed) — Raised to highest setting and verified boiler goes through normal startup cycle? Lowered to lowest setting and verified boiler goes off?

❏Measured natural gas input? (per page 25)

❏Checked incoming gas pressure by connecting 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 operation.

❏Set room thermostat to desired room temperature (and DHW aquastat, if installed, to desired DHW storage temperature)?

❏Reviewed all instructions shipped with this boiler with owner or maintenance person?

❏Fill in Installation certificate on page 27.

❏Return instructions to envelope and give to owner or place inside boiler housing.
