"According to your Stratton MK3 Series Boiler installation manual, terminals 11 and 12 are typically designated for external control connections. Could you confirm whether these terminals require programming to perform a specific function? Some boilers need configuration within the control settings to recognize external switching inputs—does this apply to the Stratton MK3 Series Boiler? If so, what steps are necessary to carry out this setup?"

INSTALLATION The boiler is delivered with: - A plan for helping fix the boiler to the wall. - Two mounting hooks. - A 4 bar (models below 70 kW) or 6 bar (models above 80 kW) safety valve. - A plastic funnel that is adapted to the safety valve. - A siphon and a flexible hose for evacuating condensates. - An information plate for the 40 to 120 kW models switching to propane gas. - A gas adapter for the 70 to 120 kW models switching to propane gas. The boiler must not bear the weight of the accessories and connections IMPORTANT: (hydraulics, gas, exhaust system, etc.). 4.1. Installing the boiler The use of the fixing hooks supplied with the product or our supports WARNING : is mandatory.
  • Page 23 STRATTON MK3 - Installation, Use and Maintenance STRATTON MK3 boilers must not be mounted on a wall covered with an inflammable material: plastic, wood, etc. The combustion air must be free of agents containing chlorine, ammonia, fluorine and alkaline. These compounds are found in aerosols, paints, cleaning products, washing powder, detergents, glue, snow- clearing salt, etc. Do not draw in the air that is evacuated from places where these products are used - swimming pools, laundries, hair dressing salons, cold rooms - as one or more of these compounds could be introduced into the combustion air.

  • Page 25 STRATTON MK3 - Installation, Use and Maintenance 4.3.1. Ventilation BOILERS NOT EXCEEDING 70kW The ventilation requirements of these boilers is dependent on the type of flue system used, and their heat input. All vents must be permanent with no means of closing and positioned to avoid accidental obstruction by blocking or flooding. Detail reference should be made to BS. 5440 Pt. 2. In IE refer to the current edition of I.S. 813. The following notes are for general guidance only: If installed as a room sealed appliance in a room or internal space, then no purpose provided ventilation is required. If installed as an open flued appliance in a room or internal space, then a permanent air vent is required. The sizes given below are for vents directly communicating with outside air. For other situations refer to BS. 5440 Pt. 2. In IE refer to the current edition of I.S. 813 Ventilation Requirements (not exceeding 70kW net Input) when installed in a compartment. If installed in a compartment, then permanent air vents are required at high and low level.
  • Page 26 STRATTON MK3 - Installation, Use and Maintenance 4.3.2. Connection to a B23 chimney B23 type connection: Air from the installation premises, gas evacuation through the roof via a natural draft pipe.

  • Page 28 STRATTON MK3 - Installation, Use and Maintenance The combustion product extraction duct must be dimensioned by using the parameters set out in the table in chapter 3.3. Depending on the actual configuration of the duct, a calculation is IMPORTANT: required to check that the pressures at the boiler outlet at Qmin, Qall and Qn do not exceed the maximum allowable values in this table.
  • Page 29 STRATTON MK3 - Installation, Use and Maintenance 4.3.4. Assembling the flue Flue terminals or extension ducts may be cut to shorter lengths if required When cutting a duct ensure it is square by marking the length all the way around and only cut back the plain end. When cutting concentric duct, it is important that the inner duct is maintained at 20mm longer than the outer duct to allow correct connection of the ducts. Care should be taken to support the inner duct when cutting the flue. When assembling only use water as a lubricant. Note. Horizontal flue runs must be angled down between1.5° - 3° towards the water heater to allow the condensate to drain. For this reason, it is recommended that a support bracket is used for every 1m of extension pipe. See below for flue assembly examples.
  • Page 30 STRATTON MK3 - Installation, Use and Maintenance 4.3.5. FLUE TERMINATION POSITION IMPORTANT INFORMATION Install the flue in accordance to BS 5440:1 2008 Position the terminal, so the products of combustion do not cause a nuisance. The flue is secured in the wall using either sand and cement or heatproof silicone. The flue must be supported by a bracket every meter of flue length and at every change of direction. Due to the high efficiency pluming will occur. For this reason, vertical termination is recommended, and in any case, terminal positions which could cause problems should wherever possible be avoided.
  • Page 31 STRATTON MK3 - Installation, Use and Maintenance 4.3.5.1. Horizontal flue positions Refer to table 1 4.3.5.2. VERTICAL FLUE POSITIONS Refer to table 1 HEAT INPUTS IN EXCESS OF 70kW NETT For boiler installations with total heat inputs in excess of 70kW nett, reference should be made to BS6644 and IGEM/UP/10.

Condensate removal Check that the removal of condensate is not obstructed, on both the boiler side and the pipe side. 6.2. Gas supply Check that the gas pipe diameter is correctly sized: It is necessary to stop all the boilers together abruptly using the boiler room main circuit breaker to check that the gas pressure regulator safety device is not triggered. If this is triggered, the gas pipe is undersized. After this operation, reengage the circuit breaker. The boilers must start automatically, if not, consult the supplier of the gas pressure regulator.

The AGU2.550 interfaces are used to control the two three-way regulating valves of the heating networks. The other 2 will be controlled by the RVS63 integrated in an external unit. The boiler operates in variable flow temperature according to the outdoor temperature measured by the exterior sensor QAC 34, without a low temperature limit.

HYDRAULIC DIAGRAM Figure 28 - MK3-20 diagram The boiler operates in variable flow temperature according to the outdoor temperature measured by the exterior sensor QAC 34. The heating water law is programmed on the NAVISTEM B3100, with or without a low temperature limit and with a weekly programme. The heating pump must be able to operate at a constant speed to ensure the minimum flow rate that is required by the generator. If the installation is equipped with thermostatic taps on the emitters, the bypass between the outward and return lines of the network is essential. It is equipped with a differential valve that allows for the free flow of the heating pump when the thermostatic taps close.
