1.0 Introduction

1.1 Introduction
1. Your Baxi Combi 133 - 100 - 80 HE Plus are gas fired,
room sealed, powered flue condensing combination
boilers, providing central heating for your home and mains
fed domestic hot water. It is fully automatic and does not
have a pilot light. Boiler frost protection and pump
protection are an integral part of the appliance.
2. Due to the high efficiency and the resulting low flue gas
temperature a white plume of condensate will be emitted
from the flue outlet terminal. This will be particularly
evident during periods of low outdoor temperatures.
3. The very high efficiency of these boilers also results in
the flue gasses cooling to the point where part of their
moisture content condenses inside the boiler, giving up
further heat as it does so. The condensate is drained to a
suitable disposal point through the plastic waste pipe at the
bottom left of the boiler. This must must not be modified
or blocked.
4. Priority is given to the hot water mode - when a hot
water tap is turned on the supply of heat to the central
heating circuit is interrupted.
1.2 Operating the Boiler
1. The externally mounted Baxi Intellistat, integral Baxi 12
Hour Timer Kit or other type of clock should have been
fitted in your system, together with heating controls. Full
instructions on the use of these controls will have been
supplied with them.
2. Hot water will always be available when a hot tap is
opened.
3. Central heating will be available if the Summer/Winter
switch is set to Winter and the timer (or other clock) is set
correctly. It is also dependent on the setting of any room
thermostats or thermostatic radiator valves. Refer also to
Section 3.2 Protection & Precautions on Page 5.
To access the control panel, hinge down the lower door
panel (Fig. 1).
When the boiler is in its standby state, the only visible light
should be the Green ‘Mains ON’.

2.1 Temperature Control
Central Heating
The boiler will automatically achieve the optimum flow
temperature for maximum comfort and efficiency.
1. However, in the case of the elderly, infirm or very young,
a lower radiator surface temperature may be desirable. If
so, the central heating flow temperature can be adjusted
between approx 55 °C minimum and approx 82 °C
maximum by turning the Central Heating Maximum
Radiator Temperature Control Knob (Fig. 2).
2. The boiler will light automatically on demand and the
Green ‘Burner ON’ light will be lit whilst water is being
heated (Fig. 2).
3. Priority is given to domestic hot water. The boiler
control system has an automatic time delay built in for
central heating. It is normal that following a shutdown by
the boiler thermostat, timer or other heating control, there
is a delay of around 3 minutes, before re-lighting.
Domestic Hot Water
The boiler will automatically achieve the optimum flow
temperature for maximum comfort and efficiency.
1. The temperature of the domestic hot water can be
adjusted between approx 45 °C minimum and approx
55 °C maximum by turning the Domestic Hot Water
Temperature Control Knob (Fig. 2).
2. The boiler will light automatically on demand. The Green
‘Domestic Hot Water ON’ light will be lit from the tap
being opened until the tap is shut and water has been
heated to the set temperature. The Green ‘Burner ON’
light will be lit whilst water is being heated. (Fig. 2).
Intelligent Pre-Heat: The boiler incorporates an intelligent
pre-heat feature. This ensures that the domestic hot water
to the tap is pre-heated only when the user required hot
water the previous week. The pre-heat switches the boiler
on for approximately 1 minute every 40 minutes when
required. During the first week of operation from power
on, no pre-heating will occur.
Summer/Winter Button
Summer setting (Button Out) - hot water will be provided
when a tap or shower is turned on. Central heating will be
off even if the Timer or other control is set to On.
Winter setting (Button In) - central heating will operate on
demand or the hot water will be provided when a tap or
shower is turned on (Fig. 2).
