D) Description of Operation
Important: The heater must NOT be
controlled by switching ON and OFF the
main electrical supply to it.
1) Standard Units
The ignition sequence commences each time the external
controls e.g. Time clock, room thermostat etc. call for
heat. The internal exhaust fan will run and, when sufficient
combustion airflow is proved by the air pressure switch, the
ignition spark will be generated, the main gas valve opens
and the burners light. The heater fan will automatically
start approximately 2 minutes after the burners light.
When the external controls are satisfied the burners will be
turned off and approximately 2 - 3 minutes later the heater
fan will be automatically stopped. If the burners fail to light
the control box will make another four attempts at ignition.
2) High / Lo & Modulating Units
When the burners are alight, the heat output will be
controlled either to high fire or low fire or, in the case of
modulating units, to any point between high and low fire;
depending on the requirements of the space being heated
and the controls system.
3) Summer / Winter Modes
Certain types of external controls will provide for two
modes of operation i.e.
Summer: The heater fan alone will run at the dictate of the
external controls to provide air movement.
Winter: The heater will operate normally.
4) Fan and Limit Control
The fan and limit controls are mounted towards the top of
the air heater inner bulkhead and are accessed via the front
door.
i) Main Air Fan MAN / Auto
When the white button is pushed in the fan will run
continuously i.e. not controlled by any external controls
e.g. Time clock. When the white button is pulled out the
fan will start and stop automatically in conjunction with
the burner.
ii) Limit Thermostat
This operates if high temperatures within the heater are
detected, the burners are turned off and a red indicator
light inside the heater is illuminated. The fault condition
must be identified and rectified and the thermostat
manually reset.
When the unit has cooled push the reset switch on the
front of the heater to reset the limit thermostat interlock
relay, the red indicator light will go out and the unit is
operational again.
If the heater has not been left operational
proceed as follows.
A) Checks before lighting the Air Heater
The following preliminary checks should be made before
lighting the heater(s)
a) Ensure that the ELECTRICAL supply to the heater is
switched OFF.
b) Check that all warm air delivery outlets are open.
c) Check that the thermostat is set at MAX.
d) Check that the clock control is set to an ON period.
e) Check that any other controls are calling for heat.
B) Lighting the Air Heater
1. Switch on the electrical supply at the isolator
2. If the Limit indicator light comes on press the limit
interlock reset switch inside the heater.
3. The startup sequence will commence. After a short
delay the burners will light.
4. If the burners fail to light the control box will
automatically restart the ignition sequence. If after 5
attempts at ignition the burners have still failed to light the
control box will go to lockout and the amber lockout light
inside the heater (or on the low level remote reset, MC200
or Powrtrol RR if fitted) will be illuminated. To restart the
ignition sequence depress the reset button on the low
level reset for about 1-2 seconds.
WARNING: If it is not possible to light the
heater after several attempts, contact the
installer or local service company.
C) To Shut Down the Air Heater
1) For Short Periods:
Turn the room thermostat to the OFF, or set to it’s lowest
setting.
2) For Long Periods:
Complete step 1 above. Wait for 5 minutes and then turn
OFF the electrical supply at the isolator.

VPC Range Users, Installation & Servicing Instructions Doc Ref M202 issue 5.5 Aug 2018.
Note: The limit thermostat(s) can only be reset
once the unit has cooled down.
Unless the cause of the fault condition is
readily obvious, for example a power cut whilst
the heater was operating, a service engineer should be
contacted.
E) Maintenance
To maintain efficient, reliable and safe operation of the
heater it must serviced by a qualified person at least
annually and preferably at the end of the heating season.
IMPORTANT
Free access must be maintained to and around
the heater for servicing purposes and the air
supply to the heater must not be restricted
in any way. Combustible materials must not be stored
adjacent to the heater.
If at any time a gas leak is suspected, turn OFF the gas
supply at the meter and contact the local gas undertaking
immediately.
All Powrmatic heaters use gas and electricity
to power them, they may also contain moving
parts such as pulleys and belts. It would be
hazardous to tamper with or attempt to
service unless you are a competent person in the field of
Gas and Electrical work.
If you have any safety questions reference the servicing
and installation of any of our heaters please do not hesitate
to contact our head office for expert advice. Your safety is
paramount to us.
Gas Safety (Installation & Use) (Amendment)
Regulations
It is law that all gas appliances are
installed, adjusted and, if necessary,
converted by qualied persons* in
accordance with the current issue of the
above regulations. Failure to install appliances
correctly can lead to prosecution. It is in your own
interests and that of safety to ensure that the law is
complied with.
* An approved class of person listed on the gas safe
register.
The VPC range are highly efficient gas fired, fanned
circulation floor standing air heaters that cover heat
outputs of 30kW to 130kW. The units have a single closed
flue system that can be either vertical or horizontal and
feature a single burner assembly which as standard is ON/
OFF but can also be supplied in High/Low or Modulating
formats. High/Low or Modulating formats give a turn down
facility of approximately 2:1. The heaters are certified for
use on Natural Gas, Group H - G20, and Propane - G31 only.
Appliance Categories are Cat II2H3P (GB, IE).
The heaters intended primarily for heating commercial
or industrial premises. They must not be used where the
atmosphere inside the premises could be contaminated
e.g. Dust, oil mist etc. or in areas classified as hazardous as
defined in BS 5345: Part 2. They are not suitable for siting
externally.
VPC heaters feature a closed combustion circuit and have
an internal exhaust fan, mounted downstream of the
heat exchanger, to evacuate the products of combustion
and draw in air for combustion. The air heater must be
connected to a flue system that is approved by Powrmatic
Ltd.
They may be used where the atmosphere inside the
premises could be contaminated e.g. Dust, oil mist etc. but
the heaters are not airtight and therefore may not be used
in areas classified as hazardous as defined in BS 5345: Part 2
or areas subjected to significant negative pressures due to
extract systems.
VPC heaters have a centrifugal fan assembly fitted at the
base of the heater to circulate the air being heated past the
formed tube heat exchanger.
Heaters are fitted as standard with inshot burners, a fully
automatic control for ignition, flame sensing, gas supply
control and safety functions, an internal exhaust fan, main
air fan and fan/limit thermostat.
Options include High/Low or Modulating burner controls,
inlet duct connection, outlet duct connection, 90° outlet
bend and a full range of modular duct components.
IMPORTANT
Service and Maintenance Engineers shall
ensure that replacement items are tted,
adjusted and set in accordance with the
data and detail set out in these instructions. If in doubt
consult Powrmatic Technical Department.
