Access & passwords

Installer and service menu codes, and how to get into them.

Open the Installer Menu (CodE, password 0300)

Boiler · Glow B85/B120/B160

Installer parameters (2.xxx) sit behind a 4-digit code entered in the CodE sub menu. The code is 0300 (not printed in the manual; from Glow Brand). Entering it also makes the System Test (0.200) visible in the user menu.

1. From the main screen press RESET/ENTER to open the main menu.
2. Press DHW up until CodE is highlighted, then RESET/ENTER.
3. Enter 0 - 3 - 0 - 0: set each digit with DHW up/down and confirm with RESET/ENTER; after the fourth digit the Installer Menu (2.000) opens.
4. Back out one level with CH up or CH down. The menu closes by itself after 4 minutes without a key press.

Button combinations

Key presses that open menus, show readouts or switch modes.

Navigate the menus

Boiler · Glow B85/B120/B160

Four arrow buttons plus RESET/ENTER drive the whole control.

1. RESET/ENTER once = main menu; DHW up/down moves between 0.000 (user), 1.000 (information) and CodE.
2. Select a parameter with RESET/ENTER; the value blinks; DHW up/down changes it; RESET/ENTER stores it.
3. CH up or CH down cancels an edit or goes back one level.

Service & test modes

Forced fan, low and high fire, test and diagnostic modes, error history and live data.

Read error history and live data (Information Menu 1.000)

Boiler · Glow B85/B120/B160

The information menu is read-only and does not need the installer code.

1. 1.051 = last 16 lockouts, 1.052 = last blocking error, 1.031 = last error number.
2. 1.008 = flame current in uA (needs more than 1.5 to keep the burner on).
3. 1.053 flame failures, 1.054 successful ignitions (x16), 1.055 failed ignitions, 1.056/1.057 burner hours CH/DHW (x10), 1.058 total run days.
4. 1.040-1.043 actual, ignition, minimum and maximum fan RPM; 1.033 CH pressure; 1.006 flue temperature; 1.063 0-10 V input.

Run the system test (fixed fan / low / ignition / high fire)

Boiler · Glow B85/B120/B160

Parameter 0.200 appears in the user menu only after the installer code has been entered. Used for combustion setup; the boiler locks in CH mode so a heat load must be available. It times out on its own.

1. Enter the installer code in CodE, leave the installer menu and open the user menu (0.000).
2. Select 0.200. The main screen shows tESt alternating with the active test.
3. Step through tests with CH up/down or DHW up/down: OFF, FAN (fixed fan speed), Lo (minimum power), Ign (ignition power), Hi (maximum power), REg (maximum power limited by supply temperature), Stb (max thermostat test), LCO1 (low water cut-off test).
4. For combustion analysis pick Hi, wait 5 minutes, measure CO2/CO at the 1/2 in. test port in the exhaust adapter, then check Lo as well.

Reset & cancel

Clearing lockouts, service reminders and fault history; skipping purge or de-air programs.

Cancel the 14-minute de-air sequence

Boiler · Glow B85/B120/B160

On every power-up (parameter 2.139 = 1) the control runs a 14-minute de-air cycle (dAir) and ignores calls. If the system is already purged you can skip it.

1. Hold CH down and DHW down together for at least 3 seconds while dAir shows.
2. To change when it runs: 2.139 = 0 runs it every 24 h, 1 after every power cycle (default), 2 disables it.

Clear a lockout

Boiler · Glow B85/B120/B160

Hard lockouts (Loc) are not cleared by cycling power.

1. Hold RESET/ENTER for at least 2 seconds on the display.
2. For software lockouts also press the small reset button on the back of the ICB.
3. Too many resets in a row triggers Err 134; then cycle power and fix the real cause.

Reset the service reminder (wrench icon)

Boiler · Glow B85/B120/B160

A blinking wrench means the service interval has elapsed.

1. In the installer menu open 2.203 and choose Reset (the parameter can also be switched On/Off).
2. 2.204 sets the interval in days (30-1275, default 1000).

Settings shortcuts

Where the useful parameters live and what they are set to from the factory.

Change display units and run the display test

Boiler · Glow B85/B120/B160

User-level settings, no code needed.

1. 0.901 = temperature unit C/F, 0.902 = pressure unit bar/psi.
2. 0.997 lights every LCD segment; press any button to leave.

Commissioning

Start-up and set-up steps that are easy to miss.

Set the appliance type for CPVC / high temperature venting

Boiler · Glow B85/B120/B160

Factory setting limits flue temperature to 149 F for PVC. For CH or DHW setpoints above 140 F the vent must be CPVC and the control must be told.

1. Set 2.138 to 52 (B85/B120 NG), 53 (B160) or 55 (B85/B120 LP) for a 194 F flue limit; 50, 51 and 54 are the PVC defaults.
2. Raise 2.024 (max CH setpoint) and 2.003, and for DHW 2.091 and 2.115, to the required values up to 180 F.
3. Exceeding what the vent allows gives Loc 16.

For licensed technicians. Installer menus, test modes and access codes change settings that affect safety; only use them if you are trained on the appliance and understand the result. Gas, electrical and refrigerant work must be done by a qualified, licensed person, and the manufacturer’s manual for the exact model and local codes always take priority.
