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.
To maintain efficient, reliable and safe operation of the
heater it must serviced annually by a qualified person.
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.

The LNVx range are highly efficient, gas fired, fanned
circulation air heaters that cover heat outputs of 15kW to
140kW, have a closed combustion circuit and are supplied
complete with a flue system.
LNVx heaters are certified for use on Natural Gas, Group
H - G20, and Propane - G31 only. Appliance Categories
are Cat II2H3P (GB, IE). All LNVx heaters are CE certified
and conform to all the European directives stated in
section 1.3.1
LNVx heaters are designed to be suspended from suitable
roof points or alternatively to be mounted on purpose
designed brackets and are intended primarily for heating
commercial or industrial premises. All variants are for
internal use only.
LNVx 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.
LNVx heaters 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.
LNVx F, LNVx Duo and LNVx V heaters have an axial fan
assembly fitted to circulate the air being heated through
the formed tube heat exchanger. LNVx CCF units are
supplied with a centrifugal fan and LNVx D units for use
with ducted systems where the air moving fan is by
others or a centrifugal fan section is used adjacent to or
remote from the heater. LNVx DH units are for use in air
handling units.
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 (F and CCF models), and fan/limit thermostat.
Options include High/Low or Modulating burner controls,
inlet duct connection, outlet duct connection, 30°, 45°
head, 90° outlet bend, vertical/horizontal outlet louvre
assembly and a full range of modular duct components.
IMPORTANT
Service and Maintenance Engineers shall
ensure that replacement items are fitted,
adjusted and set in accordance with the
data and detail set out in these instructions. If in doubt
consult Powrmatic Technical Department.
