Prestarting
11.1.
1) Switch the boiler off (see p.
and throw a cover of a front panel;
2) Unscrew 6 self-threading screws from front
panel's support;
3) remove a front panel with a cover;
4) Put off a plastic cap from the regulating
screw C and Б
(see schemeScheme
Checking gas inlet pressure in the regulator
11.2.
1) Unscrew a gauge on 1...2 turns from the control point B and connect a manometer;
2) Switch a boiler on and render it to the CH mode (see p 3.2.4, page.9);
3) Set rated power by turning on a function of gas analysis (see p.
4) Keep boiler in the CH mode within 1 minute;
5) Check gas pressure in the control point В. It should be 1,3 kPа – 2,0 kPа
(130 - 200 mm of water column) for NG and 2,9 kPа (300 mm of water column) for LPG. In other case it is
necessary to Switch the boiler off and address to the emergency service of gas facilities, telephone number 04
or replace a cylinder (for LPG);
6) Render boiler into stand-by mode consequently pushing a button К5 (see p.
7) Disconnect a manometer and wrap a gauge in the control point until bumping.
Regulating rated pressure
11.3.
To perform regulating rated pressure you must effectuate the following:
1) Unscrew a gauge on 1...2 turns from the control point А and connect a manometer;
2) Switch the boiler on and render it to the CH mode (see p.
3) Set rated power by turning on a function of gas analysis (see p.
4) Keep boiler in the CH mode within 1 minute;
5) Check gas pressure in the control point А. It should be 1 kPа (105 mm of water column) for NG and 2,5 kPa
(250 mm of water column) for LPG. In other case to adjust pressure by an adjusting screw C while keeping an
internal screw B from turning over.
11.4 Regulating minimal pressure
1) Disconnect a cable from the terminal Е, boiler will render to the minimal power and on the display will be
mapped an error «07» (see p.14.1, page 29);
2) Check gas pressure in the control point А. It should be 0,15 kPа (15 mm of water column) for NG and 0,3 kPа
(30 mm of water column.) for LPG;
In other case to adjust pressure by turning the adjusting screw Б, while turning over an external screw С;
3) Connect cable to the terminal Е.
11.5
End of operation
1) switch the boiler off;
2) disconnect manometer and wrap a gauge in the control point A until bumping;
3) put a plastic cap on the adjusting screws C and Б;
4) Switch the boiler on and render it to the CH mode (see p.
5) check the gas leakage in the control points А and В (see p.
6) render the boiler into a stand- by mode consequently pushing a button К5;
7) install a front panel and fix it by means of 6 self-threading screws;
8) close a cover of the front panel.
RENDERING A BOILER TO ANOTHER TYPE OF GAS
12.
Type of gas, which a boiler is adjusted to, is indicated on the boiler body's data plate and user's manuals (see
