2 Important Information
2.1 Safety instructions
When carrying out work on the heating sys-
tem, such as cleaning and maintenance, wear
appropriate protective equipping when re-
quired.
There is a danger of getting injured through:
burning, knocking against corners and edges,
crushing in moving parts and noise.
Mains supply: 400V C
In a risky situation, the PYROT can be discon-
nected from the electrical mains at all the leads by
the master switch on the control cabinet
Doors
CAUTION
FIRE HAZARD:
The boiler plant must never be operated with
the doors open! Red-hot objects that might
escape could result in fires.
RISK OF INJURY:
If the doors are open during operation, sparks
or flames could leap out.
Equipment for dissipating excess heat
The operational reliability of the thermal run-off
safety valve should be examined annually by a
competent specialist. The safety heat exchanger
must not by any means be used as an operational
heat exchanger.
Seals
For the functioning and controllability of the
burner, it is important that no unwanted air can
leak in, entering unchecked through leaky spots.
The doors and lids have to shut tight
−
any dam-
aged seals must be replaced immediately.
Tighten the retaining screws and handles snugly.
Operation, cleaning & maintenance
Bear in mind that only if operated and maintained
properly can even the best of products fulfil their
functions well, doing so for a long time and free of
malfunctions.
Compliance with the "Cleaning" section is manda-
tory!
2.2 Excess temperature/power failure
CAUTION
DANGER OF THIS SUDDENLY GOING UP IN
FLAMES:
Do not open the doors or lids on the boiler
plant!
-
Switch on additional heat consumers.
-
The exhaust fan goes out of operation.
-
The temperature-limiting safety switch triggers.
-
The valve for the thermal run-off safety valve
opens at approx. 95°C. The excess heat is
conducted off into the channel.
If the temperature-limiting safety switch
(TLSS) has triggered, then it has to be manu-
ally unlocked. The TLSS is situated at the top
of the boiler.
To reset, unscrew the black cap and press the
button.
NOTE: Only as of a temperature of approx. 70°C
resetting is possible.
Possible causes for excess temperature:
-
Incorrect setting on the control module.
-
Defective
component
of
the system (pump or
valve).
-
Sudden drop in output to zero. The feed auger
still has to be emptied. The heat yet produced
by this can result in surplus temperature. Acti-
vate "DISSIPATE SURPLUS HEAT" function!
2.3 Low water/excess water pressure
Possible causes:
1. Low water: Leakage in the heating system.
2. Excess water pressure: The expansion system
not functioning.
In either case, one should have the facility exam-
ined by a competent heating installer.
Unlock this malfunction with either the reset
button for the water level control system or for
the overpressure monitor, and by pressing the
OK key on the control panel.
