Utica Boilers UB95M-200 Installationsanweisungen

Start boiler after completing all instructions in 

Installation, Operation and Maintenance Manual.

Start boiler by turning thermostat up to call for heat.

Once boiler has started and is operating, continue 

startup procedure by performing all following steps to 

set and verify operation of controls.

Verify Space Heating Mode
A.  Press “Mode” button until display shows [PARA]. 

This is parameter mode.

B.  Press “Step” button until first digit of display shows 

“3.”

C.  Last digit must show “1.” If any other number 

displays, press “+” button until “1” shows in right-

hand digit, then press “Store” button to save this 

setting.

Set space heating target temperature
A.  Press “Step” button until first digit of display 

shows “4.” Last three digits show outlet water 

temperature setting.

B.  Press “+” or “-” buttons to change setting to 

desired outlet water temperature. Factory default 

setting is 180°F.

• Outdoor sensor installed: Setting is target 

temperature for outdoor temperature at or 

below factory setting (32°F). At higher outside 

temperatures, control module calculates target 

temperature.

• When summer/winter switch is used, closing 

switch will disable boiler (space heating) circulator 

during summer operation.

• Outdoor sensor not installed: Setting is target 

temperature at all times.

C.  Press “Store” button to save setting.

If control is already in parameter mode , skip step 1 (below) 

and proceed to step 2.

Press “Mode” button until display shows  [PARA] 

(parameter mode).  

Press “Step” button until first digit of display shows “2.”

Last digit must show “1.” If another number displays, 

press “+” button until “1” shows in right-hand digit, 

press “Store” button to save this setting.

Control module turns on DHW circulator when indirect 

water heater operating control closes. Control module 

shuts off boiler circulator (stops space heating) during 

calls for DHW heating. 

Information below presented in brackets “[ ]” represents 

actual boiler control panel display with first digit indicating 

boiler status and last three digits showing measured boiler 

water temperature. (Ex.- [A180] indicates status of “A” and 

boiler water temperature of 180°F.)

Turn down DHW aquastat on DHW tank (if used). If 

necessary, turn off power and remove one of DHW 

aquastat wires to ensure boiler will not receive DHW 

heat call.

Turn off power to boiler at service switch.

Wait few seconds, then turn on power to boiler.

• [180] Self-check on power-up for a few seconds.
• [0180]  No call for heat.

Raise room thermostat to call for heat.

• [5180] Blower/boiler circulator on. Blower and boiler 

circulator energize and control checks for air flow.

• [1180] Pre-purge. Blower speed will increase to ignition 

speed. Blower will run in pre-purge for 10 seconds.

• [2180] Ignition. After pre-purge, control module opens 

gas valve and starts ignition spark.

• If burner flame proves within 4.5 seconds, burner 

continues to fire. Burner will fire at startup rate for 

about 10 seconds to allow flame to stabilize.

• If burner flame does not prove within 4.5 seconds, 

control module attempts ignition sequence again. 

Flame must prove within 6 attempts or control will 

lockout (display will show [E 02]).

• Verify flame failure operation by closing boiler manual 

gas cock to prevent gas flow. Open manual gas valve 

after testing.

• [3180] Burner on, space heating. Once flame is 

proven and stable, burner turns down to low fire for 

approximately 2 minutes.

• After this low fire period, burner is allowed to modulate. 

Firing rate depends on actual outlet water temperature 

versus target temperature.

Allow boiler to bring water temperature to target 

temperature.

• [6180] Target temperature reached. Burner shuts 

down. Blower runs in post-purge (see below), then 

turns off. Boiler circulator continues to run as long as 

there is call for heat.

Lower room thermostat to stop call for heat.

Instructions in this manual are based on factory 

default parameter settings.
