Standard Height Frame & Header Kits

2.2 MULTIPLE BOILER INSTALLATIONS

For installing 2 to 6 boilers, the product range includes water and gas headers capable of assembly using threaded socket,

compression and flange connections.

2.3 HYDRONIC ISOLATION: LOW LOSS HEADER & PLATE HEAT EXCHANGER

A low loss header or plate heat exchanger allows flow separation within a hydronic system.

This allows two flow circuits to operate with their own flow and pressure drop environments whilst effectively transferring heat to its

adjoined water circuit.

This enables the modern high resistant, high efﬁciency boilers to operate under their optimum conditions, while the main heating circuit

operates to its own controlled optimum requirements.

2.4 OUTPUT CONTROL

All pumps are designed to be wired to the appliance to allow a controlled pump over run.

If using an external pump control system the capability of a timed pump over run signal provided by the appliance must be maintained

at all times.
The optional Varican accessory control can be installed (1 per boiler) to enable cascade control.

2.5 GAS SUPPLY

For Evomax the 30, 40, 60, 80, 100, 120 & 150 boilers are conﬁgured for use with natural gas. The 30P, 40P, 60P & 80P boilers are

conﬁgured for use with LPG / Propane.

For Evomax 2 the 30, 40, 80, 60, 100, 120 & 150 boilers are conﬁgured for use with natural gas. The 30P, 40P, 60P, 80P, 100P & 120P

boilers are conﬁgured for use with LPG / Propane.

Connection to the gas supply must be in accordance to with all the applicable regulations.

A single frame and DN50 water header kit will require the gas inlet to be made up to the gas tap provided, connecting it to the inlet of

the appliance.

2, 3, 4 and 6 boiler units will be supplied with a 2” gas header and all the necessary components and pipe work to connect it to the

appliances.

Note: Test points are provided at each end of the 2” gas header. The test point nearest to the gas inlet is intended to be used as the

appliance inlet pressure point.

2.6 ASSEMBLY

The frames must be located in a suitable place that affords a flat and level floor-area of suitable load bearing capacity. Care must be

taken when locating the frames that space is available for the servicing, installation and maintenance of the appliance and all of the

associated connections and equipment. (See Appliance manuals)

When using multiple frames they must be bolted together and where necessary secured to the floor.

2.7 SAFE HANDLING

Installation may require 2 or more operatives to move it to its installation site, remove it from its packaging base and during movement into its

installation location. Manoeuvring may include the use of a sack truck and involve lifting, pushing and pulling.
Caution should be exercised during these operations.

Operatives should be knowledgeable in handling techniques when performing these tasks and the following precautions should be considered:
• Grip the boiler at the base.

• Be physically capable.

• Use personal protective equipment as appropriate, e.g. gloves, safety footwear.

During all manoeuvres and handling actions, every attempt should be made to ensure the following unless unavoidable and/or the

weight is light.

• Keep back straight.

• Avoid twisting at the waist.

• Avoid upper body/top heavy bending.

• Always grip with the palm of the hand.

• Use designated hand holds.

• Keep load as close to the body as possible.

• Always use assistance if required.
