1.0 Duct Mounted Burst Fire Heater
This Burst Fire Heater should only be used as a supplementary
heater in conjunction with specified MVHR Ventilation Unit:
AP-MVHR-RL/LL-QA9837.
The AP EH 500 heater unit is a duct mounted heater, with an electric
heating element. The heater is supplied with a burst fire output
controller and room mounted temperature set-point adjustment
control unit.
The heater is intended to provide individual room temperature
control as a supplement to the LPHW heating supply integrated with
the MVHR ventilation unit, providing typically 30 % of the heating
load of the room.
On application of a heating enable signal (volt free) from the central
controller, and verified fan operation, the electric heater control is
enabled, and the room occupant is able to adjust the set-point
controller to the required temperature.
2.0 Installation of the Heater
Installation must be completed by qualified personnel only.
The Heater must be fitted indoors away from any water spray or
source of steam.
Heater to be secured directly to ceiling slab and then rectangular
ducting(by others) fitted directly to inlet and outlet spigots.

3.0 Burst Fire Heater General Specification
The electric heater assembly shall be constructed of galvanised mild
steel (natural finish).
The heating element shall be of steel sheathed type, and be rated at
500W output with a 230V 50 Hz 1ph supply.
The heater enclosure shall be thermally insulated with approximately
10mm of mineral fibre insulation materials. (This level of insulation
is considered appropriate for operation within a warm ceiling void
adjacent to the room served).
Manual Re-Set Button
The unit shall incorporate a thermal overload device requiring
manual re-set if tripped by over-temperature. Unit will only re-set
when power is on.
Fig 2. Manual re-set.
The device is rated for airstream operation only, and lack of, or
failure of air flow will cause over- temperature, and the operation
of the thermal overload.
(Sized to interface with 204 x 60mm plastic ducting (push fit
connection ports are provided), the minimum air flow rate for
the standard device is approximately 8 l/s).
The assembly shall include a mounting plate with fixing holes, and
shall include the Burst fire controller.
Connection terminals shall be provided for mains and control
connections (The unit does not incorporate a means of electrical
isolation).
Unit current rating:-
3 A Fusing requirement :-
5A Power supply 1 ph. 230V 50 Hz AC.
This unit must be earthed
N.B. Control cables should not be routed within 50mm
of mains supply cables.

9.0 Certification
To comply with EC Council Directives 98/37/EC Machinery Directive and 2004/108/EC
(EMC).
To be read in conjunction with the relevant Product Documentation (see 2.1)
1.0 GENERAL
1.1 The equipment referred to in this Declaration of Incorporation is supplied by Nuaire to
be assembled into a ventilation system which may or may not include additional
components.
The entire system must be considered for safety purposes and it is the responsibility of
the installer to ensure that all of the equipment is installed in compliance with the
manufacturers recommendations and with due regard to current legislation and codes
of practice.
2.0 INFORMATION SUPPLIED WITH THE EQUIPMENT
2.1 Each item of equipment is supplied with a set of documentation which provides the
information required for the safe installation and maintenance of the equipment.
This may be in the form of a Data sheet and/or Installation and Maintenance instruction.
2.2 Each unit has a rating plate attached to its outer casing. The rating plate provides
essential data relating to the equipment such as serial number, unit code and electrical
data. Any further data that may be required will be found in the documentation.
If any item is unclear or more information is required, contact Nuaire.
2.3 Where warning labels or notices are attached to the unit the instructions given must be
adhered to.
3.0 TRANSPORTATION, HANDLING AND STORAGE
3.1 Care must be taken at all times to prevent damage to the equipment. Note that shock
to the unit may result in the balance of the impeller being affected.
3.2 When handling the equipment, care should be taken with corners and edges and that
the weight distribution within the unit is considered. Lifting gear such as slings or ropes
must be arranged so as not to bear on the casing.
3.3 Equipment stored on site prior to installation should be protected from the weather and
steps taken to prevent ingress of contaminants.
4.0 OPERATIONAL LIMITS
4.1 It is important that the specified operational limits for the equipment are adhered to
e.g. operational air temperature, air borne contaminants and unit orientation.
4.2 Where installation accessories are supplied with the specified equipment eg.
wall mounting brackets. They are to be used to support the equipment only.
Other system components must have separate provision for support.
4.3 Flanges and connection spigots are provided for the purpose of joining to duct work
systems. They must not be used to support the ductwork.
5.0 INSTALLATION REQUIREMENTS
In addition to the particular requirements given for the individual product, the following
general requirements should be noted.
5.1 Where access to any part of equipment which moves, or can become electrically live are
not prevented by the equipment panels or by fixed installation detail (eg ducting), then
guarding to the appropriate standard must be fitted.
5.2 The electrical installation of the equipment must comply with the requirements of the
relevant local electrical safety regulations.
5.3 For EMC all control and sensor cables should not be placed within 50mm or on the same
metal cable tray as 230V switched live, lighting or power cables and any cables not
intended for use with this product.
6.0 COMMISSIONING REQUIREMENTS
6.1 General pre-commissioning checks relevant to safe operation consist of the following:
Ensure that no foreign bodies are present within the fan or casing.
Check electrical safety. e.g. Insulation and earthing.
Check guarding of system.
Check operation of Isolators/Controls.
Check fastenings for security.
6.2 Other commissioning requirements are given in the relevant product documentation.
7.0 OPERATIONAL REQUIREMENTS
7.1 Equipment access panels must be in place at all times during operation of the unit, and
must be secured with the original fastenings.
7.2 If failure of the equipment occurs or is suspected then it should be taken out of service
until a competent person can effect repair or examination. (Note that certain ranges of
equipment are designed to detect and compensate for fan failure).
8.0 MAINTENANCE REQUIREMENTS
8.1 Specific maintenance requirements are given in the relevant product documentation.
8.2 It is important that the correct tools are used for the various tasks required.
8.3 If the access panels are to be removed for any reason the electrical supply to the unit
must be isolated.
8.4 A minium period of two minutes should be allowed after electrical disconnection before
access panels are removed. This will allow the impeller to come to rest.
NB: Care should still be taken however since airflow generated at some other point
in the system can cause the impeller to “windmill” even when power is not present.
8.5 Care should be taken when removing and storing access panels in windy conditions.
