Hydraulic Connection - Joannes EPOCA 25-29 NS Installation And Maintenance Manual

HYDRAULIC CONNECTION

Fit the supporting hooks and attach the assembly template, moving it up to the wall; fit all the pipes, starting
with the end pipe fittings already mounted on the template: system supply, system return, cold water, hot water,
any gas pipes and electric mains leads with room thermostat.
Once the pipes have been fitted, the end pipe fittings can be removed and ordinary caps fitted, ready for
hydraulic tests to be carried out. The template can be removed or, if left in place, will be embedded in the wall
once finishing operations have been completed (plaster and tiles); only the two supporting hooks will protrude
from the wall, as well as an opening for the connections. Attach the boiler to the hooks through the holes at the
back of the frame, push it up against the finished wall and fit the two lock nuts onto the hooks.
Make the necessary hydraulic connections using the pipes/tubes supplied, cutting them to the right length,
depending on the distance between the fittings on the boiler and those on the template embedded in the wall.
CONDENSATE DISCHARGE
The condensate which forms inside the boiler must
be discharged. The boiler is therefore fitted with a
water trap. The water trap fitting must be connected
to a outlet in PVC. It is advisable to insert another
water trap on the discharge line before entry into
the waste water system.
Important: should the condensate discharge pipe
(supplied with the boiler) be replaced, always
use a pipe with an internal diameter of at least
13 mm.
The coo condensate unloading in endowment is
of Ø 25 mm external.
