  • Suitable for houses up to 150 m2
  • Up to 90% heat recovery
  • Extra low energy use
  • Mechanical summer by-pass
  • Internal humidity sensor
  • Digital control

Boost can be achieved with almost any type of sensor or switch including momentary 

Integral Humidity Sensor

The integral humidity sensor (models with H suffix) increases speed in proportion to relative humidity levels, saving energy and reducing noise.The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature

Construction

The outer enclosure is constructed of PVC with the inner body being constructed of EPP

Motors

The unit has 2 x low energy, high efficiency EC/DC motors

Installation
Spigot Options The combination of spigot options allows installation in confined locations. If vertical and horizontal connection is required on the same outlet/inlet, additional spigots can be supplied. The condensate drain can be taken out through the back, side or bottom of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation

ACCESSORIES:

In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.

Installation Guide


Vent Axia BH 1st Fix



  1. Position vent axia BH unit proverbially on a wall or vertical timber frame with provided wall bracket

  2. It is possible to take pipes from either the top of side of unit

  3. Duct connections RHS unit -rear left is extract from house-front left is supply air to living areas- rear right is air intake from outside - front right is air to outside

  4. Install wiring for controllers (see bottom of page for further details)

  5. Install condensation drain from unit to internal or external drain

  6. Install wall /Soffit vents or roof vents (Minimum 1.5 meter apart) Pipes are 125mm diamater

  7. Position distribution boxes in the chosen location (proverbially in a central location minimising duct lengths )

  8. Install silencer (if specified) to air supply distribution box

  9. Install solid rigid ductwork and between distribution boxes and MVHR unit, (If possible allow for insulated flexible ductwork for final connections of MVHR unit )

  10. Install radial pipe into the distribution box ,

  11. Cut to length and install pipe into ceiling plenum, (insure you install rubber seal onto pipe) secure pipe in place with fixing band or pipe clips


Warning! There can be either one or two pipes going from the distribution box to the plenum depending on the required airflow , Always check plan that will indicate 1 or 2 pipes Install insulated rigid or insulated flexible ductwork to external vents Seal all open pipes to prevent debris and moisture ingress


 


Vent Axia BH 2nd fix



  1. Trim ceiling Plenums to height of plasterboard (Easier to do before plastering ceilings)

  2. Install air valves to plenums (slightly open valve by two turns)

  3. Install all controllers

  4. Check that condensation drain has been fitted

  5. Switch unit on and follow the set up procedures

  6. Check air flow rates and commission system



Initial Design -


Pre designed plan - Please follow the plan ensuring the correct number of pipes to each area - Please note the plan is only a guide and you may have to reroute pipe work differently and re position valves to suit layout of rooms


No Plan - If a design is not possible due to renovation, Retrofit or properties with multiple obstacles simply follow the listed recommendations


We would recommend that you



  • Install 2 x pipes from the distribution box to the room air plenum if air flow requirement exceed 10 L/s or if length over 15 meters  

  • Install 2 x pipes from the distribution box to the air extract plenum in the main shower rooms and Kitchen

  • All other areas only require a single pipe from the distribution box to the room air plenum

  • Radial ductwork is suitable to be fitted below your loft insulation providing superior heat retention Insulate any ductwork or Manifold/ Distribution boxes with a minimum of 25mm thermal duct wrap that go above insulation in unheated attic spaces

  • Slim-line manifolds are suitable for installation to concrete ceilings and only require a 100mm service void

  • Position supply plenums approx. 500mm from corner of wall (avoid areas above beds and wardrobes)

  • Position extraction plenums to outside of showers and above kitchen sink (not cooker)

  • Only extract from a room with a open appliance (stove) if there is a supply with equal or higher airflow
