Need help?Do you have a question about the Heatilator DVBV4842-B-KIT and is the answer not in the manual?
This document outlines the installation and maintenance procedures for the Heatilator NDV/NBV Upgrade Kit, designed for various Heatilator fireplace models including DVBV4842-B-KIT, DVBV4236-B-KIT, DVBV3933-B-KIT, and DVBV3630-B-KIT. The kit is compatible with specific NDV and NBV series models, such as NDV3630I-B, NDV3630IL-B, NDV3933I-B, NDV3933IL-B, NDV4236I-B, NDV4236IL-B, NDV4842I-B, NDV4842IL-B, NBV3630I-B, NBV3933I-B, NBV4236I-B, and NBV4842I-B. The primary function of this upgrade kit is to enhance or replace internal components of existing Heatilator gas fireplaces, specifically focusing on the aesthetic and functional elements that simulate a wood-burning fire.
The kit includes several components crucial for the fireplace's operation and appearance. These include:
The upgrade kit is designed to be integrated into existing Heatilator gas fireplaces, transforming or refreshing their internal appearance. The installation process involves several steps, beginning with the removal of existing components. Users will first need to remove the old hearth pan and log set, followed by the pilot shield and the false back. This preparatory phase ensures a clean slate for the new components.
A critical aspect of the upgrade is the installation of the new log set. The logs are fragile and must be handled with care to prevent damage. The manual provides detailed instructions and diagrams for placing each log correctly on the hearth pan. For instance, Log #4 is positioned by aligning its left end with a flat spot on Log #2 and resting its right end on a flat spot on Log #1. Log #5, with its forked end, is placed towards the front of the appliance, with slots on its back side resting on a bent lip of the hearth pan, and then slid to the right until it contacts a log pin. These precise placements are essential for achieving the intended realistic flame pattern and visual effect. The manual includes a table (Table 1) that specifies the corresponding log set and individual log part numbers for different Novus model sizes (3630, 3933, 4236, 4842), ensuring that the correct components are used for each fireplace model.
After the logs are installed, the new false back is assembled and placed into the appliance. The new flue visor is then installed, with specific instructions to bend both legs of the flue visor toward the back of the firebox. The pilot shield is installed on top of the pilot assembly, and finally, the new hearth pan and its assembly are placed into the appliance. The final steps involve adding embers and lava rock, following the instructions provided in the appliance's main installation manual, and installing the two top logs as detailed on previous pages of this upgrade kit manual.
The overall usage experience after the upgrade is intended to be seamless, providing an enhanced aesthetic and potentially improved performance for the gas fireplace. The realistic log set, glowing embers, and properly installed internal components contribute to a more authentic and visually appealing fire.
While the manual primarily focuses on installation, it implicitly highlights several maintenance considerations through its warnings and instructions.
The fact that this is an "Upgrade Kit" suggests that components like logs, embers, and internal panels may degrade over time due to heat exposure and regular use. The availability of specific part numbers for individual logs (e.g., SRV2380-071 for LOG 1 of size 3630) indicates that these components are designed to be replaceable. This modularity simplifies maintenance, allowing users to replace individual worn or damaged parts rather than the entire fireplace.
Although not explicitly detailed in this upgrade kit manual, the presence of embers and logs implies a need for periodic cleaning to remove dust, soot, or debris that may accumulate during operation. The removal and reinstallation steps outlined for the upgrade kit provide a template for how these components would be accessed for cleaning. For example, to clean the hearth pan or the area beneath the logs, the logs would need to be carefully removed, cleaned, and then reinstalled following the same precise placement instructions. The main appliance installation manual would likely contain more specific cleaning instructions for the glass and internal components.
The pilot shield (E) is installed over the pilot assembly. While this shield protects the pilot, periodic inspection of the pilot assembly itself for proper function and cleanliness is a standard maintenance practice for gas appliances. The shield's design allows for access to the pilot when necessary for cleaning or troubleshooting.
In summary, the Heatilator NDV/NBV Upgrade Kit provides a comprehensive solution for refreshing or enhancing the internal components of compatible Heatilator gas fireplaces. Its usage involves a detailed, step-by-step installation process focusing on precise placement of aesthetic and functional elements. Maintenance considerations, though not exhaustively detailed in this specific manual, are implied through safety warnings, the modular design of replaceable components, and the inherent need for periodic cleaning and inspection common to all gas fireplace appliances. The emphasis on careful handling of fragile logs and adherence to safety warnings regarding hot surfaces are paramount for both installation and ongoing use.
