1. Introduction

1.1 Grant SpiraPod Outdoor Enclosure

Figure 1-1: Front/right side view of Grant SpiraPod

1.2 Description

The Grant SpiraPod is a weatherproof housing for the external installation of the Standard Grant Spira

5/18, 6/26 or 9/36 wood pellet burning condensing boilers. It is constructed from 1.0mm, 1.5mm, and

2mm thick Galvanised steel, finished with a polyester powder coating in ‘Grant Grey’.

It is supplied fully assembled, with the pellet hopper and pellet auger fitted, ready for the installation of the

Grant Spira boiler. The integral pellet hopper has a capacity is 180 kg.

The Grant SpiraPod incorporates several doors and covers to allow easy access to the boiler for the

installation commissioning and servicing of the boiler contained within.

1.3 Pellet Hopper

The Grant SpiraPod pellet hopper has a capacity of approximately 180 kg. This is accessed by lifting the

hinged hopper lid on the top of the SpiraPod so that pellets can be tipped into the hopper by the user.

The hinged hopper lid is fitted with two gas struts to assist with opening and closing. This lid MUST BE

CLOSED after filling to prevent any water/rain entry

The hopper is fitted with a contents sensor. This detects when the level of pellets in the hopper falls to a

pre-set minimum level (approximately 20 kg) and, if a bulk pellet store is used, triggers the operation of

either a bulk store auger, or vacuum system, to deliver pellets from the bulk store. If no bulk store is used,

the contents sensor will stop the burner operating when the minimum pellet level is reached.

Topping up the hopper with more pellets will automatically operate the contents sensor and the burner

will restart (if there is a demand for the boiler to run). The hopper must be topped up with a further 10kg

(total of at least 30kg) of pellets to restart the boiler.

The electrical connection to the boiler is made to the 4-way electrical plug on the factory-fitted ‘flying lead’

from the Spirapod wiring centre, located at the front of the pellet hopper. Refer to both Section 8 of these

Installation Instructions and Section 8 of the Spira Installation & Servicing Instructions for electrical

connection details.

1.4 Flue System

The design of the Grant SpiraPod allows for the standard Grant Biomass flue system to be used. Refer to

Section 7 of these Installation Instructions and also Section 7 of the Installation & Servicing Instructions

supplied with the boiler.

1.5 Frost Protection

The Grant SpiraPod is supplied with a factory fitted frost protection thermostat. This is located inside the

SpiraPod enclosure on the rear of the SpiraPod wiring centre (located at the front of the pellet hopper).

Refer to Figure 1-2. It is pre-wired to the boiler SpiraPod electrical wiring centre and factory set to 2°C.

Grant recommends the use of a Pipe Thermostat (not supplied) in conjunction with the Frost thermostat

to avoid unnecessary and wasteful overheating of the property. This pipe thermostat should be located

on the boiler return pipe and set to operate at 25°C. Refer to the Section 8 of the Installation & Servicing

Instructions supplied with the boiler for details of the pipe thermostat electrical connections.

For total system protection against freezing, particularly during extended periods without electrical power,

Grant recommends the use of a combined heating system antifreeze and corrosion inhibitor, used in

accordance with the manufacturer's instructions.

1.6 Access

The SpiraPod enclosure is fitted with the following means of access:

A pair of hinged doors (with lockable door catch*) at the front –for access to the boiler for

routine cleaning (emptying the ash pan), access to boiler/burner controls and the Vacuum

system controls (if fitted).

A hinged hopper lid (with lockable door catch*) on the top left side –to allow pellets to be tipped

into the hopper by the user.

A hinged cover panel (with internal catch) on the top right side –to allow access to the top of the

boiler for Commissioning and Servicing.

A removable door panel (with lockable door catch*) at the rear –to allow access to the electrical

wiring centre and rear of boiler for commissioning and servicing.

* These door catches can be fitted with a small padlock (not supplied) if required.

To unlock and open any of the above, unlock/remove the padlock (if fitted). Rotate the knob of the catch

clockwise to unlatch and open the front door or pellet hopper lid. On the rear access door panel rotate

the knob anticlockwise to unlatch and remove. Close and lock the door, lid or panel using the reverse of

the above procedure.

3. Installation Information

3.1 Regulations

The Installation of a Grant SpiraPod and Spira wood pellet boiler must be in accordance with the Building

Regulations and any local Byelaws, Water Regulations, British Standards and any other relevant

legislation. Refer to Section 4 of the boiler Installation & Servicing Instructions boiler for further details.

Refer to Local Building regulations for minimum distances between the SpiraPod and combustible

materials.

Check with the Local Authority regarding the possible need for Planning Permission for an external boiler.

3.2 Boiler location

The Grant SpiraPod can be installed either against the building or 'free standing' some distance away

from the building. Refer to Figures 7-4 and 7-5.

If the ‘free standing’ option is chosen, then the boiler flue system must be at least 2300mm away from

any buildings or structure that are higher than the flue outlet. See Figure 7-4. If this distance cannot be

achieved, then the SpiraPod will have to be located with the right hand side close to or against the

building and the flue system extended such that the terminal is above the eaves of the roof. Refer to

Figure 7-5.

The Grant SpiraPod must be positioned such that sufficient clearance is provided for maintenance,

servicing and filling the pellet hopper. In particular the following minimum clearances are required around

the SpiraPod:

Rear: 800mm (to remove panel and access to rear of boiler/hopper)

Front:1500mm (to open doors and install/commission/service boiler)

Pellet hopper side: 600mm (to access pellet hopper and open pellet hopper lid)

3.3 Base

The Grant SpiraPod must stand on a solid, level non-combustible surface capable of supporting both the

weight of the boiler when full of water, and the weight of the enclosure/pellet hopper when full of pellets.

Refer to Section 2 of these Installation Instructions for weights.

Grant recommends a prepared concrete standing (at least 150mm thick) with a smooth finish on the top

extending beyond the enclosure base at least 100mm all around.

3.4 Installation of SpiraPod

The Grant SpiraPod is supplied fully assembled, with the pellet hopper and pellet auger fitted, ready for

the installation of the Grant Spira boiler.

Position the SpiraPod in the required position/orientation on the concrete base and secure it to the

concrete, using suitable fixings (e.g. Rawlbolts or similar) through the two holes provided in the base at

the front of the enclosure. Refer to Figure 3-1.

Eight triangular steel shims are supplied with the boiler. These can be fitted under one or more corners,

as and when necessary, to level the SpiraPod (BEFORE securing it to the concrete base).

3.5 Installation of the Spira boiler

With both the front doors open and the rear access panel removed:

Remove the corner bracket from the top right hand corner of the front door opening. Refer to

Figure 3-2. Keep this bracket, and the four fixing screws, as this will need to be replaced once

the boiler is installed.

IMPORTANT

BEFORE fitting the boiler into the SpiraPod, It is essential that the pellet auger is rotated, as detailed

below, to ensure that the end of the auger outlet does not come into contact with the side of the boiler

during the installation process.

The auger is not fastened to the pellet hopper but is held in position by a bracket that fits over the

auger housing. Refer to Figure 3-3.

To rotate the auger; grasp the auger motor and auger outlet and carefully pull the auger out by

about 50mm until the auger mounting bracket is clear of the auger housing. Refer to Figure 3-4.

Rotate the auger clockwise until the auger outlet is facing directly downwards. Carefully allow the

auger to fall back into the auger housing until the bracket rests on the end of the auger housing

with the outlet still pointing directly downwards. Refer to Figure 3-5.

Remove the burner from the combustion chamber door of the boiler, taking care not to damage

the white gasket between the door and burner. Refer to Section 11.7 of the Installation &

Servicing Instructions supplied with the boiler for guidance on removing the burner.

Lightly lubricate the base area (using WD40 or similar lubricant). Do not use washing up liquid, or

anything similar, for this purpose as this may stain the base of the SpiraPod.

Position the boiler inside the SpiraPod, with the combustion chamber door facing forwards, and

align the sides with the two guide rails on the SpiraPod base. Refer to Figure 3-1

Carefully push the boiler towards the back of the SpiraPod enclosure until the rear edge of the

boiler base reaches the stop rail at the back.

NOTE: This process may be easier if a rope or similar (e.g. a lifting strop) is placed around the

base of the boiler and out of through the rear of the enclosure. The boiler can then be

simultaneously pulled and pushed into position against the rear stop rail.

Once in position it is not necessary to secure the boiler down to the base of the SpiraPod

enclosure.

Remove and discard the front section of the left hand guide rails, to allow the boiler combustion

chamber door to fully open. Unscrew and remove the rail fixing screws to remove this section of

guide rail only.

Fit the pellet feed tube to the burner so that the open end faces towards the left. Refer to Section

4.1.1 of the Installation & Service Instructions supplied with the boiler for details on the fitting of

the pellet feed tube.

Refit burner to the combustion chamber door and reconnect the two plugs from the boiler control

panel. Refer to Section 11.9 of the Installation & Service Instructions supplied with the boiler.

Fit the pellet feed tube thermostat lead onto the thermostat terminals. Refer to Section 10.5 of the

Installation & Service Instructions supplied with the boiler for details on the fitting of the pellet

feed tube thermostat lead.
