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.
Above all, install the water heater in accordance with official standards (Gas installation regulations. Royal Decree
1853/1993, 22 October 1993) which are mandatory and have been included in an excerpt on pages 16 to 19.
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 15).
1.2. Ensure that the facility's premises meets all the conditions required by the
Regulations (see pages 16 to 19). Pay particular attention to complying with everything
outlined in the Regulations concerning:
"Combustion air inlet and burnt gases outlet" (I.T.C.) MI-IRG 05.
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.
