6.5.5.2 Brackets, mounting
Air inlet
• The first bracket should be mounted 0.5 mtr away from the boiler
• Horizontal and non vertical pipes should be bracketed equally divided with a maximum distance of 1
mtr between the brackets
• Vertical pipes should be bracketed equally divided with a maximum distance of 2 mtrs between the
brackets
• In case of a chimney shaft, first identify the air inlet. The end of the air inlet pipe should be at least 0.5
mtr above the shaft. The last component before entering the shaft should be fixed. If a bend is the last
component also fix the component before the bend.
Flue exhaust
• A bracket must be mounted to every component except in the case that the length of the pipe befo-
re and after the bend < 0.25 mtr. In this case mount the first bracket at a length of max 0.5 mtr away
from the boiler
• Horizontal and non vertical pipes that have a distance between the fixing brackets > 1 mtr should be
equipped with a non clamping (to allow minor movement) bracket in between
• Vertical pipes should be bracketed equally divided with a maximum distance of 2 mtrs between the
brackets
• In case of a chimney shaft, first identify the flue outlet. Check if the used shaft pipes are damaged or
blocked.The ends of the exhaust pipe should be at least 0.5 mtr above the shaft. The last component
before entering the shaft should be fixed. If a bend is the last component also fix the component
before the bend.
All brackets must be obtained from M&G
6.5.5.3 Seals and joining
• Prevent incorrect or damaged seals by shortening pipes squarely and by deburring after shortening.
•
Joins or connections in the exhaust flue may not be screwed.
• In the air inlet only aluminium or stainless steel joins or connections may be screwed. It is not allo-
wed to screw PP joins or connections.
• Do not use glue or foam like silicon or PUR.
• To assure soundness all components must be sealed.
• For smooth joining only use a soap solution (1% in water). Do not use oil, grease or (acid free) Vase-
line
Important notice
If instructions as written above are not followed and or the materials for air inlet and flue gas exhaust
as quoted above are not used Mark Climate Technology can not be held responsible for eventual conse-
quences.
6.6 Electrical connection
1. The electrical installation should be in accordance with national and local codes and regulations.
2. As standard the boiler is configured for 400 VAC + 3N/50Hz
3. The terminal strip is accessible by opening the side cover (unscrew with screw driver) behind which
the control is mounted.
4. A means of disconnection must be incorporated in the fixed wiring in accordance with the wiring ru -
les. Use the cable guide indicated with a 400 VAC +3N/50 Hz sticker on the backpanel of the boiler.
As it is a stationary appliance without means for disconnection from the supply a contact separation
in all poles that provide full disconnection under voltage category III must be provided. The minimum
cross section of the supply wire is 5 x 2.5 mm2 and must be connected to the circuit breaker 400V 4
