INSTALLATION INSTRUCTIONS
The water heater must be installed by a professional that holds an AUTHORISED GAS INSTALLER PERMIT.
The smooth
operation of your COINTRA water heater depends largely on it being installed CORRECTLY.
This task will be easier if you follow the guidelines below:
1.
MODEL, PREMISES AND LOCATION.
1.1. Pay particular attention to ensure the chosen water heater is suitable:
- To satisfactorily cover the facility’s hot water needs.
- For the intended gas (see water heater data plate).
- In relation to the water pressure in the network necessary for it to work (see specification table on page
12).
1.2. Ensure that the facility’s premises meets all the conditions required by the
Regulations.
1.3. Position the water heater as near to the hot water tap as possible, near the
sink but NEVER above the cooker. It should also be placed as near as possible
to the flue or the point where the pipe that disposes of burnt gases comes out.
2. PIPES.
2.1. Make the hot water pipes as short as possible. Isolate long sections to avoid heat loss.
2.2. Leave the ends of the cold water (F) and hot water (C) pipes as shown in the diagram. Avoid unnecessary bends and
bottlenecks. We recommend using a minimum diameter of piping of ½” and ¾” in the case of low water pressure. Make sure air
pockets are unable to form in the hot water conduit. Flush water pipes.
2.3. Connect the stopcock, which was supplied with the water heater in the accessories bag, to the hot water pipe.
