4 COMMISSIONING AND SERVICING
4.1 Commissioning – Approximate time to complete: 2 hours
Note: It is the responsibility of the installer to ensure that the appliance is properly
commissioned by Warmflow, or other trained and competent Engineer. Failure to do so
WILL invalidate ALL warranties.
The commissioning process consists of 8 main steps – familiarise yourself with all of the
steps before proceeding:
1. Ensuring the boiler is undamaged and correctly installed on site
2. Mechanical and heating system checks
3. Electrical checks
4. Assignment of required parameters
5. Initial firing of the appliance
6. Drop test mode check
7. Flue gas analysis
8. User introduction to the appliance
STEP 1 – Ensuring the boiler is undamaged and correctly installed on site.
Ensure the installation requirements listed in section 3 of this manual have been met, and
complete any remedial actions before proceeding with the commissioning procedures. Visually
inspect the appliance to ensure no damage has been caused during transportation or
installation, reporting this before proceeding. The IP (Ingress Protection) rating of the product
should be maintained by the use of correct cable glands and pipework grommets for installed
items. Ensure no foreign objects are obstructing the flue or combustion chamber, and the area
is safe for persons in the area before proceeding.
STEP 2 – Mechanical and heating system checks.
Ensure the heating flow and return pipes are identified, routed and secured in compliance with
current codes of practice. Also the heating system should thoroughly cleansed, flushed and
neutralised, then filled with appropriately concentrated corrosion inhibitors and antifreeze as
recommended in Section 3 of this manual. Ensure all air is correctly vented from the system
both within the property, and at the boiler before proceeding to the next section. Ensure the flue
pipe has been secured correctly to the appliance, and other structures if required. The operation
of the flue stabiliser must also be checked. The position of the counterweight should be per
Figure 63, and the flap should move freely without binding through its range of movement.
