Frost Protection; Condensate Drain; To Light The Boiler - IDEAL Imax Plus II F90 Installation And Servicing Manual

TO LIGHT THE BOILER

1. Switch on the electricity supply to the boiler and check that all
external controls e.g. programmer, room thermostats, etc.
are calling for heat.
2. Set the On/Off switch on the boiler to ON.
The boiler will commence the ignition sequence, supplying
heat to the system when required.
TO SHUT DOWN THE BOILER
1. For short periods
Set the parameter 2 to '00'. Note. the boiler will still fire in
frost protection mode.
2. For longer periods
Set to OFF the on/Off switch on the boiler. Isolate the mains
supply to the boiler. For longer periods the entire system
should be drained, including the domestic hot water supply.
TO RELIGHT THE BOILER
1. After Short Periods
Reset parameter 2 to the desired setting.
2. After Long Periods
The system should be re-filled, commissioned and tested by
a CORGI registered installer, or in IE a competence person,
in accordance with the Installation & Servicing Instructions.

FROST PROTECTION

The imax plus II boiler has built into its control system the facility
to protect the boiler only against freezing.
Note.
This may not protect remote parts of the system, in which case a
separate frost thermostat should be fitted.

BOILER LOCKOUTS
When a burner module locks out, the corresponding red reset
button illuminates on the fascia. If the entire boiler locks out, an
error message is displayed (see Frames 46 & 47 of Installation
& Servicing Instructions).
To reset the boiler, press and hold the illuminated red reset
buttons of each failed module and press the reset button on the
fascia.
Note.
If it is known or suspected that a fault exists on the boiler then it
MUST NOT BE USED until the fault has been corrected by a
CORGI registered installer, or in IE a competent person.

CONDENSATE DRAIN

The condensate drain must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler or leakage from the
condensate trap mounted on the bottom of the boiler.
If freezing is suspected and the pipe run is accessible an
attempt may be made to free the obstruction by pouring hot
water over the exposed pipe and clearing any blockage from the
end of the pipe. If this fails to remedy the problem the
assistance of a CORGI registered installer, or in IE a competent
person, should be sought.
ESCAPE OF GAS
Should a gas leak or fault be suspected contact your local gas
supplier without delay.
Do NOT search for gas leaks with a naked flame.
