11 Commissioning
instructions
Before commissioning
Only authorised personnel can curry
out this operation.
The correct operation and fixing of the heater is
prerequisite for the warranty. Checking gas lines and
flue system is not included in this service.
Check the function of the following equipment:
Exhaust flue
Combustion air supply
Control
unit
Safety equipment
Safety of electrical circuit
Pay attention when commissioning!
Vaporization of remaining grease of
metal units may cause greasy mist.
This kind of mist disperses after
approx. 30 minutes. During this time
the room has to be ventilated.
Adjusting nominal thermal load at
single-stage operation
Attention!
The pressure control unit is pre-
adjusted on natural gas / propane. Do
not put the appliance into operation
uncontrolled.
Adjusting the nozzle pressure
1. Open first the gas cock which is at the end of the
flexible gas hose (Fig.23, page 26).
2. Open the test nipple connection pressure.
Connect the pressure measuring instrument to the
test nipple and determine the connection
pressure.
Close the test nipple after the measurement!
3. Open the test nipple nozzle pressure.
Connect the pressure measuring instrument to the
test nipple and determine the nozzle pressure.
4. Turn the adjusting screw on the pressure regulator
slowly in the “+” or “-” -direction while continuously
watching the pressure measuring instrument. Stop
turning as soon as the required nozzle pressure is
reached. The required nozzle pressure for natural
gas H (W
o,B
=50.0 MJ/m
3
) is shown in table 5
page 14.
5. Remove the protection cap
A
(see Fig. 24, page 26).
6. Put the radiant tube into operation
7. Turn the adjusting screw
B
(see Fig. 25, page 26)
on the pressure regulator slowly in the “+” or “-” -
direction while continuously watching the pressure
measuring instrument. Stop turning as soon as
the required nozzle pressure is reached.
8. Put the protection cap
A
on the valve after the
adjusting.
9.
Close the test nipple after the measurement
and check if the test nipple is gas-tight.
Checking adjustment
1. Turn the adjustment screw slightly to “-“
-direction. Nozzle pressure must drop
immediately. If this does not happen, you must
readjust the jet pressure until the point is reached
at which a decrease or increase in the nozzle
pressure is noticeable on the measuring
instrument.
2.
Close test nipple after the measurement!
3. Remove the measuring instrument and check if
the test nipple is gas-tight.
