LRP and LK WARM AIR HEATER

HG0140.00_IM_036
Wait until the heater is switched on. Check that the heater
reaches its maximum power: from the LCD display, access the
REG menu, then use the Hi and Lo controls to force operation
at maximum or minimum output.
If the heater is controlled via the Smart Web/Easy, the function
shown is valid and the switches must not be reset to control the
operation from the LCD panel.
At maximum output, check again that the input pressure in the
valve corresponds to the value required; adjust if necessary.
Perform the combustion analysis to verify that the level of CO
2
corresponds to the figures in the tables in Paragraph 7.2 "GAS
Connections tables".
If the measured value is different, turn the adjustment screw
on the Venturi pipe. Loosening the screw will increase the CO
2
level, screwing it down will decrease the level.
Set the heater to minimum output, and verify that the level of
CO
2
corresponds to the figures in the tables in Paragraph 7.2
"GAS Connections Tables". If the values do not match, screw
or loosen the offset screw respectively to increase or decrease
the CO
2
level and repeat the procedure.
NOTE: The heater directly supplied to function with LPG
is set up for G31 gas. If the unit runs on G30 instead,
it is necessary to verify and possibly adjust settings
for CO
2
as shown in the tables in Paragraph 7.2 "Gas
settings tables".
7.4. S
tarting up for the first time
The LRP and LK heaters are supplied with settings entered and
tested for the gas specified on the nameplate. Before turning
on the heater, check the following:
•
make sure the gas being supplied matches the gas for
which the heater has been set up;
•
check, with the pressure intake "IN" on the gas valve, that
the valve input pressure corresponds to that required for
the type of gas being used;
•
check that electrical connections correspond to those in-
dicated in this manual or other wiring diagrams enclosed
with the unit;
•
check that efficient earthing connections have been com
-
pleted, carried out as specified by current safety regulations;
•
power on the heater with the general switch located on
the unit and insert the power plug inside the compartment.
To turn on the heater, follow the instructions below:
Check that the display shows RDY; if OFF is displayed instead,
work on the control, under FUN, and set the device to ON
;
Check that heat is being demanded by the connected control.
When ON appears on the LCD display, the heater starts the
ignition cycle.
NOTE: Frequently, when turned on for the first time,
the pilot burner cannot ignite because there is air in
the gas pipe. This will lock out the equipment. You will
need to reset the equipment and repeat the operation
until it ignites.
