PLANNING OUT THE SITE
When choosing the location of the Twin Flow the following should be taken
into account:-
1. The Twin Flow has a necessary clearance of 100mm to the side with the
isolator switches and 60 mm on the other side. It also requires 250mm
above, 600mm to the front, and enough space below for the pipework.
2. The Twin Flow should mount on a wall or suitable framework that can
hold the total weight of the system. An ideal location will minimise pipe
runs as much as possible, but also take up as little of the building
occupants living space as possible . For ease the backplate can be
mounted either way up to put the boiler left or right of the water heater.
3. There must be enough gas available for the water heater.
4. There must be water and electricity available.
5. There must be enough room and lighting to service the units.
6. The heaters should be installed in a location that is accessible for
maintenance. If the heaters are at high level, or access is by means of a
ladder, there should be a ladder or scaffolding available on site at all
times.
7. There must be suitable drainage available so that if a leak was to occur
from the heater or boiler, including a leak of hot water, it would not cause
damage to the building, furnishings, or inhabitants.
8. There must be a suitable place when using internal units to get the flues
out of the building in a safe manner. The flue terminals should be a
minimum of 2m above the ground whenever possible.
9. The weather compensation probe should be placed outside of a north
facing wall.
10. The wireless room thermostat should be placed approximately 1.5m off
the floor, away from hot and cold draughts.
